I have two computers (PC and laptop) with openSUSE 42.2 and 5.9.3. I have same error, but only in my PC, my laptop works perfect
I have updated to 5.9.4 and it still crash every time I open it. I have also a workstation where it has never crashed (regardless of the version). On the PC where it crashes, before it start to crash every time, I remember, I had some customization, creating avatars for users (but I don't remember how I have done).
