Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32.2 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
I was deleting folders in a dimap account (gmail) when kmail closed saying roughly that it couldn't store a message possibly due to no space left on disk.

Then kmail crashes.

There is space on the disk:  (All partitions have space):

$ df -H
