Application: kmail (4.10.3)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-21-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
I just searched for an email keyword on a "lot" (8 years of mail, 2 gigabytes) of folders. Worked correctly. Deselected the long list of folders and clicked on my main "inbox". Removed the keyword I was searching for from the search box and voila, crash.

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