Bug 324578

Application: plasma-desktop (4.11.00)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.11.0-4-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

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

was logging into the desktop.
I really don't know how to read a backtrace, so marked this as a possible dupe.

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