- What I was doing when the application crashed:

Happened at Login. Plasma seemed to restart automatically, so it didn't inhibit my work.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/usr/grte/v4/lib64/libthread_db.so.1".
