#2 Gnome keypresses not working

[mcdpa]

I think this is a bug, if not ... sorry ahead of time.

Problem: Switching Gnome workspaces with a mouse key press.

Steps Taken:

$ xmodmap -e "pointer = 1 2 3 6 7 4 5"

~/.imwheelrc reads:
> ".*"
> none, Button4, Control_L|Alt_L|Left
> none, Button5, Control_L|Alt_L|Right

$ imwheel -k -b "67"

Expected Result: The workspace should switch in any
window or the desktop. (other keypresses like Page_Up
or Alt_L|Right work as expected with both buttons)
