I've checked in a fix.  I haven't kept up with Emacs, it has been a busy
summer, and on top of that I broke my hand.  So if you can put this bug in its
proper state, I'd be greatful.  I'll get back into it in the fall.

bug#500: GTK Emacs stops reacting to keyboard events after cancelling menu by hitting Escape

[Andrey]

To reproduce:

0) Make sure you run GTK Emacs and the main menu is on.

1) Click on any main menu item. The drop-down menu with child items
   will appear.

2) Move mouse down so it is over one of the child items (but not
   separator).

3) Hit Escape to cancel the menu. The menu will disappear (it is the
   expected behavior).

4) Press any key. Nothing happens.

5) Click on Emacs buffer. Nothing happens. Emacs looks frozen.

To workaround:

Click on any main menu item and hit Escape *immediately*. Emacs is
back to life.

This bug is minor but may be very frustrating for novice users. I'm
ready to provide any additional info.

Good luck,
Andrey Paramonov
