Bug 749740

Description of problem:
I defined the following keys:

gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_corner_nw "<ctrl><alt>q"
gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_corner_ne "<ctrl><alt>e"
gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_corner_sw "<ctrl><alt>z"
gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_corner_se "<ctrl><alt>c"
gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_side_n "<ctrl><alt>w"
gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_side_s "<ctrl><alt>x"
gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_side_e "<ctrl><alt>d"
gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_side_w "<ctrl><alt>a"
gconftool-2 --set --type string /apps/metacity/window_keybindings/move_to_center "<ctrl><alt>s"

I can't move window for example from SW corner (Ctrl+Alt+z) to S side
(Ctrl+Alt+x). Moving from every 4 corners to every 4 side is
impossible. 
Also. I open up a urxvt terminal window, I use Ctrl+Alt+z to
move is to the lower left corner. When I open a new urxvt tab, the
window moves automatically to the center of the screen. This is where it
was before I moved it with defined key combination. Similar behaviour is
happening to other applications too and moving some applications simply
don't work (firefox).

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Define key-bindings shown before
2. Try to move windows around
3. They don't behave as expected
  
Actual results:
Windows either don't move at all, move back to its original position when keys are released or behave strange in some other way.

Expected results:
Window key-bindings should work as expected.
