Bug#348346: gnome: Confirm disappearing menu

[Phil Miller]

I can confirm that I'm experiencing similar behaviour since I upgraded
from 2.10 to 2.12. Specifically, when I click the Applications menu,
it appears for an instant and then becomes a small empty square, with
the menus still 'active' (as in, if I move the cursor over, the Places
and Desktop menus open). My observation differs in that the Desktop
menu still works fine.
