Comment 8 for bug 427712

This could be the same bug that I have observed and described in https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/427712 although here it does really not matter much what button in blender I click or even only mouse over.

Anyway, this regression appeared between commits 4d85a6b3 and 18882f4d.
file: libgl1-mesa-dri

I attach my gdb log of the crash.

please let me know if you need further information
