Bug 285883

Application: kontact (4.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
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:
kmail was receiving lots of mails and for each one asking me for conflict resolution (another bug relating to spamassassin marking)
as I cannot stop this conflict resolution, i changed the filter rule for spam to avoid checking incoming mails
as it did not stopped all waiting conflict resolution dialog, i used file -> quit to stop kmail and restart it later
after quiting there was a conflict resolution dialog still opened
when i pressed "keep left version"  kmail crashed

- Unusual behavior I noticed:

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