Description Dāvis 2015-07-17 20:56:31 UTC

Basically lockscreen were crashing and it would restart infinitely every second, generating crash dumps, filling HDD with them and hogging all CPU time making PC completely unusable.
It should just try like say 30 times and then better logout or something...

This is how journal looks like
