indicator-applet-appmenu crashed with SIGSEGV in dbusmenu_client_send_about_to_show()

[Johannes Huber]

Binary package hint: indicator-application

I was able to reproduce this problem on my pc.
I try to start unity and get the error that can be seen in the screenshot attached.
The result of this is that I have the navigation panels *twice* in the menu bar, this also can be seen in the screen.
When I now start a new program that tries to access the menu bar, i.e. a new instance of the terminal, the bar crashes and I recieve the error.
