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 ??
