Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I really don't know if these kind of crash reports are of any use. Plasma just crashed in the middle of nothing. I am working in a console (yakuake) and there are three concurrent sftp transfers running in the background which are still running after plasma restarted.
 
Plasma is crashing every now and then here (Current SVN version from last night: r1216415)
