Threaded Programs Hang When Disposing Dialogs Created Via the Global
Menu

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.
