Application: kontact (4.12)
KDE Platform Version: 4.12.0
Qt Version: 4.8.4
Operating System: Linux 3.11.0-15-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
Always when kontact exits, after a little while (1-60 seconds) the application crashes. 
It is, thus, impossible to save colours with calendars. Interestingly, the application does remember calendars between crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
