Bug 329016

Application: kontact (4.12)
KDE Platform Version: 4.12.0
Qt Version: 4.8.5
Operating System: Linux 3.11.6-4-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
Updated to KDE 4.12 today.  Have been in and out of Kontact three times.  Each time this crash occurs.  I was also receiving other updates in between using Kontact.  I assumed that there was some dependency that was causing the crash.  However I now wonder if that is the case.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
