Application: kontact (4.6 beta5) KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources) Qt Version: 4.7.2 Operating System: Linux 2.6.37-gentoo-r4 x86_64 Distribution (Platform): Gentoo Packages -- Information about the crash: - What I was doing when the application crashed: I pressed 'left arrow' in KMail to select the previous email in a folder with aggregation set. All aggregations were collapsed, so there was no actual email shown on the message list, just the aggregation headers only. The crash can be reproduced every time. -- Backtrace: Application: Kontact (kontact), signal: Segmentation fault [Current thread is 1 (Thread 0x7fcefa03a760 (LWP 25599))] Thread 2 (Thread 0x7fcee5e51700 (LWP 25600)): #0 0x00007fcef249526c in pthread_cond_wait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007fcef6aa061d in ??
