Bug 308161

Application: kontact (4.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic i686
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I've seen some Kontact crashes when the application starts, but it is not 100%. This time, it happened after a reboot of the box. After startup, a dialog prompts me for a Sieve password, and when I enter it and send it, *poof*.

I hope the trace is useful, even though I don't have all symbols.

The crash can be reproduced some of the time.

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