Application: plasma-desktop (0.3) KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2)) (Compiled from sources) Qt Version: 4.6.0 Operating System: Linux 2.6.32-ARCH x86_64 Distribution: "(none)" -- Information about the crash: I upgraded to KDE SC 4.4 beta2 from KDE SC 4.3.4. After that, plasma-desktop crashes each time it is supposed to start. I try to start it with Krunner or Konsole, but it crashes again. I guess it's a plasma theme or a plasmoid error that makes plasma-desktop crash. I hope the debugging message will help you. Regards The crash can be reproduced everytime. -- Backtrace: Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault [Current thread is 1 (Thread 0x7f81b7683780 (LWP 17141))] Thread 2 (Thread 0x7f8192bdb710 (LWP 17142)): #0 0x00007f81b35d907c in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #1 0x00007f81b386450b in QWaitCondition::wait(QMutex*, unsigned long) () from /usr/lib/libQtCore.so.4 #2 0x00007f81b0902ebc in ??

It's on Archlinux x86_64 (the bug reporting tool didn't add my distro in the bug report).
The candidate for the crash must be smooth-tasks-plasmoid.
Indeed, it is crashing in the SmoothTasks widget. You need to recompile it and check if it works, or completely remove it. If after recompiling it, it doesn't work, you need to report that to the widget's author (in the kde-look page) Regards
OK, recompilation worked nicely.

Yes, same here. Rebuild smooth-tasks and it's working fine again. Sorry for the cry wolf. I should have tested that first.

(In reply to comment #7) > Created an attachment (id=40710) [details] > New crash information added by DrKonqi > > My plasma desktop suddenly crash when I login You need to rebuild the smooth-tasks plasmoid. It's by the way an old version.
