Application: plasma-desktop (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.6
Operating System: Linux 3.10-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (jessie)

-- Information about the crash:
I lost power, and on reboot plasma now crashes on login.

X is still basically usable, but there is no bar at the bottom and nothing on the desktop. Task switching works, as do KDE hotkeys.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
