Title:
  plymouthd crashed with SIGSEGV in ply_trigger_add_handler()

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  After reboot in the symbols in the gnome titlebar are replaced by
  squares. They can be reset using gnome-tweak-tool for changing Icon
  Theme back and forth. Crash report above is generated by ubuntu. Don't
  know if it's connected to the fact that I connect different monitors
  each time I restart. Can this cause a plymouth crash?
