I forgot to mention I enable Opengl 3.1 ES since Martin seems to complain about common bugs lately. I will try to see if this crash ever happens in Opengl 3.1 GLX. 

I wonder if it is related. Oh well

Crash logs when clicking on a blutetooth icon

It seems to be easier to reproduce this crash by repeatedly clicking bluetooth and I do not have bluetooth on this laptop
