gnome-shell crashed with signal 5

[Mynk]

There are several problems when I log in the first time after boot. This is one of them. I would not know what causes this as the system boots with these errors in place and the dialogue box to report the bugs. There are other similar looking bugs already. I was not sure it is the same.

thx,
mynk
