Bug 299423

Application: kontact (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
When I delete some emails, Kontact will crash. I am pretty sure this may be a duplicate of bugs already reported, but just in case it is not I decided to report this.

The crash can be reproduced some of the time.

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