Description Hussam Al-Tayeb 2017-07-24 06:24:23 UTC 
I occasionally see this in coredumpctl after long gnome sessions. the timestamp suggests it happened on exit.
Not knowing the root cause, I asked on irc.
ptomato[m]> hussam: looks like a bug in mutter. MetaSurfaceActorX11's dispose method is being called after its XDisplay is already freed


Here is the crash trace. Maybe there needs to be a check somewhere?

GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new ticket at
  https://gitlab.gnome.org/GNOME/mutter/-/issues/

Thank you for your understanding and your help.
