Sure thing, I am still waiting for my account to be approved to get
access to debian salsa. Once I get access I'll create the merge request.

Bug description:
  [ Impact ]

  gnome-shell often crashes on logout causing annoyance to the user as
  an error report dialog is displayed at the next login.

  [ Test Plan ]

  1. Log into gnome-shell

  2. Use gnome-shell for long enough to trigger a garbage collection
  cycle: Scroll the app grid and repeatedly open the calendar from the
  top bar for 30 seconds.

  3. Log out.

  4. Verify no new gnome-shell crash files appear in /var/crash/

  [ Where problems could occur ]

  Only gnome-shell shutdown/logout is affected.
