Comment 1 Artur Puzio 2015-12-29 16:05:10 UTC 
Have you done anything special before it started crashing? Have you just installed plasma5 and it's crashing or was it working before?
Comment 2 René Krell 2016-01-06 18:46:54 UTC 
Well, it really doesn't happen any longer. Probably a problem with cached data after the update.
I will close this, probably nobody else cares in this case.
