Application: kmail (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Starting Kmail 4.8.4 after logging in.
Subsequent Kmail starts worked out OK, so this might be a low-priority issue.

The crash does not seem to be reproducible.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
