Description Matthias Nagel 2016-04-22 15:16:54 UTC
I have installed the KDE PIM suite from KDE overlay version 16.04.0, i.e.

kde-apps/kdepim-16.04.0:5
kde-apps/kdepim-addons-16.04.0:5
kde-apps/kdepim-apps-libs-16.04.0:5
kde-apps/kdepim-kioslaves-16.04.0:5
kde-apps/kdepim-l10n-16.04.0:5
kde-apps/kdepim-meta-16.04.0:5
kde-apps/kdepim-runtime-16.04.0:5
kde-apps/kpimtextedit-16.04.0:5
kde-apps/libkdepim-16.04.0:5
kde-apps/pimcommon-16.04.0:5

Severval dialogs from various KDE PIM applications make the whole application crash/freeze when those dialogs are shown. The respective dialogs are not renders properly but only the outer frame is drawn and the background is still visible. (See attached screen shot.) The dialog cannot be closed, the application is frozen and after some time-out the another dialog pops up with the message "The application [...] does not respond. Kill or wait longer?".

The affected dialogs are the reminder dialog of korgac, the delete confirmation dialog of kmail2, the delete confirmation dialog of akregator and probably some more I have not found yet. The behaviour is always reproducible. 

Interestingly, I have the same setup (same /var/portage/world file, same ebuild versions, same compiler settings, nearly same use flags) on another machine and there it works flawlessly.

Backtrace of korgac while waiting infinitely

I re-compiled my whole system with
CFLAGS="-O2 -march=core-avx2 -pipe -ggdb"
FEATURES="splitdebug compressdebug"

Then I connected to the running korgac process via
gdb /usr/bin/korgac {pid of korgac}

Then: thread apply all bt

Please report this to upstream. KDE PIM 16.04. is masked for a reason.
Comment 4 Matthias Nagel 2016-04-26 19:22:29 UTC
OK, it is reported upstream: https://bugs.kde.org/show_bug.cgi?id=362317

Is there any chance to get back KDE PIM 15.08 or 15.12 into the KDE overlay? Both worked.

No, as we already updated the eclasses to handle 16.04 and handling both makes it realy ugly.
