Bug 284218

Application: kontact (4.7.2)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:  Kontact appears to be crashing every time that I exit the program.  I have not noticed any unusual behavior, yet, while the program is open, but every time I close it, Kontact crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
