Application: kmail (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.5
Operating System: Linux 3.9-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

I selected a large mailing list folder (lkml), and while it was loading the index, I tried to open the settings/properties for the folder and the mailing list config for it. eventually it just crashed. context menu for the folder also quickly flashed repeatedly which made it hard to select an option.

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