Can you reproduce this? I cannot in 4.4.5 Yes, I can reproduce it still, using KDE 4.5.1 now. I do not need to start krunner, though. Just RMB and select "Expand Group" -> crash.

But there has been no change in the tasks applet since pre KDE 4.5 time. I additionally cannot see how the code can crash at the point that is listed in the backtrace. what settings do you have for the tasks widget? e.g. "only show windows on this desktop", etc... All not mentioned settings are unchecked. Appearance: Show tooltips, Max 2 rows Grouping and Sorting: Grouping by Program Name, Do Not Sort Filters: Only show tasks from the current desktop |
Application: plasma-desktop (0.3) KDE Platform Version: 4.4.1 (KDE 4.4.1) "release 225" Qt Version: 4.6.2 Operating System: Linux 2.6.31.12-0.1-desktop i686 Distribution: "openSUSE 11.2 (i586)" -- Information about the crash: I have 7 konsole windows open (in taskmanager I see 1 button and at its right a small up arrow with "7" below it), click RMB on it in the taskmanager and select "Expand Group". I have now 6(not 7!) konsole buttons in the taskmanager. When I now press Alt-F2 to open krunner, plasma crashed. Probably this has to do with the fact that there is a wrong number of buttons in the taskmanager? The crash can be reproduced every time. -- Backtrace: Application: Plasma Workspace (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0xb5378980 (LWP 29416))] Thread 2 (Thread 0xa6b19b70 (LWP 29418)): #0 0xffffe424 in __kernel_vsyscall () #1 0xb6aa20c2 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #2 0xb6b1909c in wait (time=<value optimized out>, this=<value optimized out>) at thread/qwaitcondition_unix.cpp:85 #3 QWaitCondition::wait (time=<value optimized out>, this=<value optimized out>) at thread/qwaitcondition_unix.cpp:159 #4 0xb6b0d88e in QThreadPoolThread::run (this=0x9051698) at concurrent/qthreadpool.cpp:140 #5 0xb6b180bf in QThreadPrivate::start (arg=0x9051698) at thread/qthread_unix.cpp:248 #6 0xb6a9d6e5 in start_thread () from /lib/libpthread.so.0 #7 0xb6a9d600 in ??
