-- Information about the crash:
- What I was doing when the application crashed:
Just switching between apps (from Firefox to Konsole). I clicked with the mouse in the middle of the window and suddenly crashed. When opened next time, same number of tabs opened but in the default path, not those working at earlier. Never happened before.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
