I also saw it happen with the GIMP last night; it could be that it's a
GTK+ thing with error boxes.  As I mentioned, it's easily reproducable;
if you sent me a patch for xmonad to isoloate the information you're
looking for, I'd be happy to run it for you.  Alternatively, I've
attached a small test case that uses GTK+ dialog boxes.  You can compile
it with:

gcc `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0` gtk-error-window-under-tabs.c

You should just need GTK+ libs for that, not the full-blown GNOME stack.

Mostly.  Tabs should never be drawn on top of a newly-created window.
Changing focus won't snap xmonad into the correct behavior, but
attempting to move or resize the offending window will.

I've attached a screenshot in case you can't compile the sample program.
