There seems to be incompatibility between Digikam 2.2 and libpng 1.5.5. After I've upgraded to libpng 1.5.5 and recompiled all the corresponding files, DigiKam starts normally but displayes no images in the albums. Running Digikam from terminal produces the following trace (which suggests issues with libpng): digikam(10430)/digikam (core) Digikam::AlbumManager::slotPeopleJobResult: Failed to list face tags QPainter::begin: Widget painting can only begin as a result of a paintEvent QPainter::translate: Painter not active QPainter::setClipRect: Painter not active QPainter::font: Painter not active QPainter::setFont: Painter not active QPainter::setPen: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::setFont: Painter not active QPainter::fontMetrics: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated Notice that DigiKam is aware that images in the file directories do exist (I can query it database), but does not display any of them most probably because it cannot generate thumbnails from images due to libpng problem. Recreating thumbnails manually from a corresponding menu does not help.

I see the warnings as well, but the program works fine otherwise- which makes me suspect the real problem is somewhere else. Please try the following things, in the following order: 1) log out, log in again- does it work? (ioslaves from old kde version still running?) 2) stop digikam, kbuildsyscoca4, start digikam, does it work? (invalid cached settings) 3) revdep-rebuild
Thanks for the prompt response! 3. I did revdep-rebuild - that did not help. 1. Logging in and out does not help. However, when starting Digikam, it complains about not bein able to start io-slave: QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in use, all queries will cease to work. digikam(8636): couldn't create slave: "Couldn't create io-slave: повідомлення klauncher: Помилка завантаження «kio_digikamalbums». " digikam(8636)/digikam (core) Digikam::AlbumManager::slotAlbumsJobResult: Failed to list albums digikam(8636): couldn't create slave: "Couldn't create io-slave: повідомлення klauncher: Помилка завантаження «kio_digikamtags». The Cyrillic warnings are in Ukrainian and say something like "warning by klauncher: Error in loading "kio_digikam{albums,tags}" 2. How do I stop kbuildsyscoca4? Or do you mean just run it? If I stop Digikam, run kbuildsycoca4 and then restart Digikam, it does not help :( But, I also get a message about crushing Nepomuk

I'm not sure where it comes from though... Please add (only for the moment) "keeptemp" to FEATURES in your make.conf This means that the build log is not deleted, even if the build succeeds. Then, please rebuild digikam and attach the build log here...
Created attachment 290751 [details] Build log That makes sense! Build log is attached. Thank you for helping me with this!
Apparently, the issue is that my environment variable DIGIKAMDEST is incorrect. I set export DIGIKAMDEST=/usr/ export LD_LIBRARY_PATH="$DIGIKAMDEST/lib:$DIGIKAMDEST/lib/kde4:$DIGIKAMDEST/lib:$LD_LIBRARY_PATH" To make sure thatb Digikam finds files like kio_digikamalbums.so located in /usr/lib/kde4/ But then, another problem arises. When I start Digikam, here is what I get: Could not open library '/usr/lib/kde4/kio_digikamtags.so'. Cannot load library /usr/lib/kde4/kio_digikamtags.so: (libgomp.so.1: shared object cannot be dlopen()ed) digikam(783): couldn't create slave: "Неможливо створити io-slave: повідомлення klauncher: Помилка завантаження «kio_digikamtags».

No idea how to deal with this (libgomp.so.1: shared object cannot be dlopen()ed) issue :(
> No idea how to deal with this (libgomp.so.1: shared object cannot be > dlopen()ed) issue :( Maybe you rebuilt your gcc recently and changed the openmp useflag from on to off? Please try running revdep-rebuild, and also try building digikam-2.3.0
Ran revdep-rebuild and upgraded to the lastest Digikam. The issue still remains :( Showfoto works without a glitch.
I also tried disabling openmp use flag and recompiling gcc. Didn't help, unfortunately.
Mystery got solved. I deleted all the libgomp* from /lib and then recompiled gcc again and Digikam started working. Curious, why would I have leftover ol libgomps in my /lib directory. I looked at the timestamps on those files and found that they were compiled ages ago (about a year ago). I guess, I can close this bug. Do you think I should let anyone supporting gcc know about this? Thanks for your helpful suggestions! Best wishes from Ukraine!
