This does **not** happen every time, in fact I cannot easily reproduce it. - Unusual behavior I noticed: The desktop froze for a moment before crashing, it was not immediate. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
