Bug 291104

Application: kmail (1.13.7)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1-686-pae i686
Distribution: Debian GNU/Linux unstable (sid)

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

Trying to refresh a saved search in a folder.

- Unusual behavior I noticed:

The search folder was showing an unreasonable number of unread messages, and indeed when I clicked it, it didn't have the right parameters.

I should note that KMail had been open for several days (one session) prior to this.

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