- What I was doing when the application crashed:
Playing Hearthsone fullscreeen on one monitor while playing music on spotify on the other monitor. Switching between the two multiple times triggered a crash.

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