Application: kmail (1.13.6)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic-pae i686

-- Information about the crash:
- What I was doing when the application crashed: While one email was being moved to the trash, I hit delete to remove another email. This seemed to cause the crash.

- Custom settings of the application: The email account is a gmail account, configured using the Google-recommended settings. The emails were aggregated by thread-starter.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
