Backtrace of kwin

Backtrace ("developer information" tab in the DrKonqi dialog) or it didn't happen ;-P (We cannot do anything on this bug otherwise, sorry) So I installed drkonqi, and now the desktop freezes when the crash occurs. The mouse works and sounds stay playing but windows, buttons etc. do not work. No drkonqi dialog appears. Sounds related to https://bugs.kde.org/show_bug.cgi?id=348834 That's gonna be fun. If there's still such stopped kwin_x11 process, you can gdb --pid 123456 2>&1 | tee kwin.dbg # please use the actual PID instead of 123456 ;-) into it, and "bt" to fetch a backtrace. Otherwise, allow it to generate a core dump export KDE_DEBUG=1 ulimit -c unlimited kwin_x11 --replace & More info: https://wiki.archlinux.org/index.php/Core_dump If drkonqi is not installed, the crashing kwin process dies when the new kwin process is launched. I'll try if I can debug it when drkonqi is installed and it hangs. (In reply to antti from comment #4) > If drkonqi is not installed, the crashing kwin process dies when the new > kwin process is launched. That's ok if you allow it to generate coredumps (a core dump can be loaded and inspected by gdb just as if it was a process - except it won't continue ;-) https://wiki.archlinux.org/index.php/Core_dump Created attachment 94891 [details]
Backtrace of kwin
Now it didn't hang even though drkonqi was installed. (A while ago I configured a new session to be started instead of restoring the previous one (System settings -> Startup and shutdown -> Desktop session). Could this have an effect?) Backtrace is in attachment. can you please provide also the output of: qdbus org.kde.KWin /KWin supportInformation That's bug #352259 - QML bug, induced by the aurorae engine. => Switch to breeze decoration. Nevertheless please also attach the supportInformation (here) *** This bug has been marked as a duplicate of bug 352259 *** Created attachment 94897 [details]

Attached supportInformation. I also changed the window decorations style (Application style -> Window decorations) to "org.kde.breeze" instead of "Plastik". |
