Comment 6 for bug 953479

I think those affected should mention if they've disabled the global menus, either directly or thru a 3rd party app
This bug is 100% repeatable by removing the appmenu* packages but not removing indicator-appmenu

It's also repeatable thru the use of that Usettings package that has come around, maybe other 3rd party apps also?

Not saying this is the only cause for this crash but either of the above is guaranteed to cause this
