Gtk Popup Menu accelerators not working

[Gaurav Jain <gaurav anywhere gmail com>]

Hi,

I'm creating a "pop-up" menu which is shown when I click inside a
button.  I added accelerators to the menu items (CTRL + B), but these
do not work.  If I explicitly pop up the menu and then click on the
menu item, then the "activate" signal is called for the menu item, but
not if I use the accelerator keys.

Attached is a sample source code that's not working below.

Please help me in finding out why this problem is coming, and how to resolve it.

Thanks,
Gaurav
