crash after panel_profile_background_change_notify

[Peter Bauer]

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
