If two modal windows strange things happen to combo widgets - gtk bug?

[Olaf Frączyk <olaf cbk poznan pl>]

Hi,
I have 2 windows, both of them have combo.
If I don't set these windows modal everything is OK.
But if I set them BOTH as modal:
create window 1 , set as modal window 1
create window 2, set as modal window 2
Then:
Widgets in window 1 become insensitive (as they should) but NOT combo!
I cannot use the "arrow" in window's 1 combo to pop down the list,
but if I use keys with arrows (on keyboard) on this combo then:
I change items in window's 2 combo!
And I get window's 2 combo callbacks running.

It looks for me as gtk bug.
I have gtk-2.2.0.
Is this a known issue?
