3. Right click on the same icon and "remove from panel"

mate-panel crash.

Comment 16 Wolfgang Ulbrich 2015-08-26 15:32:39 UTC 
stacktrace looks like we have a regression in glib2.
Maybe glib2 maintainer can help.
Comment 17 Wolfgang Ulbrich 2015-09-25 17:22:07 UTC 
After update to stable glib2 the issue is gone.
Did you disable debug options with stable release?
Also, i noticed that crashes with other application are gone now.
