Title:
  crash after panel_profile_background_change_notify

Status in mate-panel package in Ubuntu:
  Confirmed

Bug description:
  The Mate panel in Ubuntu 16.04 LTS Mate alpha1 is a bit buggy.
  1. Selecting the plugin Advanced Mate menu does not work (There is also no icon shown when selecting this menu in the panel)
  -When the Advanced Mate menu is added to the panel just a fullstop is shown on the panel, which can't  be removed afterwards. 
  2. Changing the Mate panel layout with the Mate tweak application causes SIGSEGV
  -I tried changing to opensuse layout -> SIGSEGV
