Description

xfce4-session-20190509T183109.1c49c2cd Unclear what I did. I think it was an accidental "switch user" instead of "lock screen", the icons are just too close together. From the timestamps it was apparently the relogin or whatever happens if one comes back from sddm.

Core was generated by `xfce4-session'. Program terminated with signal SIGSEGV, Segmentation fault.

so for some reason user_data==NULL is not handled. Not sure if that is supposed to happen, and the bug is elsewhere.
