Application: plasma-desktop (0.4) KDE Platform Version: 4.5.95 (4.6 RC2) Qt Version: 4.7.0 Operating System: Linux 2.6.35-25-generic i686 Distribution: Ubuntu 10.10 -- Information about the crash: - What I was doing when the application crashed: Plasma crashed immediately after deletion of a calendar event in Kontact. For me this happens very rarely, as I have KCalendar in extensive daily use and it was the first time plasma crashed on this action. The crash can be reproduced some of the time. -- Backtrace: Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault [Current thread is 1 (Thread 0xb787b940 (LWP 1721))] Thread 4 (Thread 0xaf747b70 (LWP 1726)): #0 0x029943f4 in pthread_mutex_lock () from /lib/libpthread.so.0 #1 0x003e8f66 in pthread_mutex_lock () from /lib/libc.so.6 #2 0x03a91ea3 in g_main_context_prepare () from /lib/libglib-2.0.so.0 #3 0x03a92279 in ??
