Summary: emerge of gdm-2.20.10-r2 fails with gdk-pixbuf-csource error : failed to load "./preferences-desktop-locale.png": Couldn't recognize the image file format for file './preferences-desktop-locale.png' -Following another bug report, I rebuilt libpng and gtk+. No change, same error. -I stepped back to version gdm-2.20.9-r1. No change, same error. Everything was fine. I added the xinerama use flag to my make.conf and rebuilt all the pkgs that referrenced it. My system is very current ~x86, so most packages were replace "R" and very few were update "U". There have been several bugs with this exact error message from gdm build. None of them have gotten to the root of the issue. Maybe we can solve it. Any help appreciated. ================================================================= >>> Emerging (1 of 4) gnome-base/gdm-2.20.10-r2 * gdm-2.20.10.tar.bz2 RMD160 SHA1 SHA256 size ;-) ...

SOLVED! SUMMARY: emerge librsvg gdm DETAIL: Since the build failed while using gdk-pixbuf-csource utility from gtk+ I looked into that some more. This util loads code for different graphics file formats from the below loaders dir. # ls -al /usr/lib/gtk-2.0/2.10.0/loaders ...<snip>... # gdk-pixbuf-query-loaders ...<snip>... g_module_open() failed for /usr/lib/gtk-2.0/2.10.0/loaders/svg_loader.so: /usr/lib/libxcb-xlib.so.0: undefined symbol: _xcb_lock_io So investigating further, of all the loaders in loaders dir above, only svg is provided by a package outside of gtk+. Bug #46888 gave this hint, and suggestion to rebuild librsvg to correct this. Whola!
You were trying to open a PNG file originally though, not a SVG..
This problem still persists, and the solution suggested here is, I'm afraid, totally specious. I have found that gdk-pixbuf-csource works just fine as a non-root user, but fails when run as root. The cause of this proved to be that the program scans /usr/share/mime/mime.cache when run as non-root, but not when run as root. As a work-around, I created a symlink for this file in /root/.local/share/mime/; but this is just a quick kludge. I can upload the 2 strace logs that produced this diagnosis [and produced the kludge that made gdk-pixbuf-csource work]. The correct solution is to fix gdk-pixbuf-csource so that it scans all the appropriate mime.cache files, regardless of which users runs the utility.
(In reply to comment #3) > The correct solution is to fix gdk-pixbuf-csource so that it scans all the > appropriate mime.cache files, regardless of which users runs the utility. After some more research, I have found out why the /usr/share directory is omitted: it had been removed from one of the /etc/env.d files that assign the XDG_DATA_DIRS environment variable. In my case, it was 90xdg-data-base. Once I had corrected that file and performed env-update, all was working properly again.
