I'm using the following configuration:
- Ubuntu 11.10 x64
- Awesome Window Manager v3.4.10
- Gnome 3.2
...and I got the following problem:

Every time I click on the empty space in a menubar or toolbar in a Gtk application (like Nautilus, GEdit), mouse clicks don't work any more. Sometimes it also happens after clicking a resize grip (See this bug report).
I'm still able to move the mouse cursor, but clicking and scrolling doesn't have any effect.
All keyboard actions work as before, e.g. I can switch desktops with Mod4-Left / Mod4-Right, type in text boxes or switch the active window with Mod4-j/k.
When I close the application where I did the killing click, everything works perfectly as before.
This is especially annoying when it happened in Nautilus as I have to killall nautilus to make it work again, which kills the desktop as well.
Does anybody have the same problem, and is there any bugfix around?
EDIT
I found this item in the Ubuntu Bug tracker which describes exactly this misbehavior. As far as I understand, they want to release the bugfix in the next Ubuntu version, 12.04. Is there a chance to get the update earlier? Do I have to compile Gtk myself, if yes, how to do this?
Note: I asked this, less specific, here
