Bug 273774

Application: kontact (4.4.10)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
 - I chose the krunner task manager to send TERM
 - Kontact crashed

- Reason for this:
 - very often KMail cannot be restarted (for some reason unkown to me)
 - One way is to log out, restart the machine or just to stop an existing kontact process by TERM/KILL signal

Although the bug report doesnt give any insight to me, there are some BOOST and GPG references. I'm using GPG with KMail. Maybe the professionals can use these hints.

The crash can be reproduced some of the time.

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