Bug ID: 15404
Summary: crash in xfsm_manager_get_shutdown_type
Classification: Xfce Core
Product: Xfce4-session
Version: Unspecified
Hardware: PC (x86_64)
OS: Linux
Status: NEW
Severity: normal
Priority: Medium
Component: General
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: Xfce 4.14
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.
