Bug Description

This problem was spotted on Viking (see: https://bugs.launchpad.net/ubuntu/+source/viking/+bug/1255275).

I have distilled this down to the (I think) bare minimum valid thread program that displays this fault (as attached).

Here the program will hang when dialog that is created via the Main Menu is closed.
 Goto Menu Bar -> File->Dialog->Close ---> Program Hangs

This only occurs under the Unity Desktop.
When run under another Desktop such as LXDE (lubuntu-desktop) then the program operates correctly.

Thus I assume this is a fault of this Unity GTK+ module.

I note another workaround for programs is to avoid the global menu thing by running with an empty UBUNTU_MENUPROXY environment variable.
