Application that crashed: kmail
Version of the application: 1.12.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30 x86_64

What I was doing when the application crashed:
I've run out all the disk space where KMail keeps it's storage, it obviously received some message but was unable to save it. The certain dialog box appeared, but after that KMail crashed.

 -- Backtrace:
Application: KMail (kmail), signal: Aborted
