Mutter 3.4.1 move_frame

[Clemens <clemens lab21 org>]

Hi,

I am upgrading my extension to work with Gnome 3.4 and think i have found a
bug. With 3.2 i was able to use Meta.Window.move_frame to move windows, no
mather if they use window decorations or not. With 3.4 move_frame produces a
segfault when trying to move a window without decorations (for example 
Chrome).

It is quite easy to reproduce. The shell will crash, but can be 
restarted using
"gnome-shell --replace" (Open a terminal using keybinding or swap to 
ttyX and restart
it)

1) Open Chrome and focus it with the mouse
2) Execute in LookingGlass: (true/false makes no difference)
      global.display.focus_window.move_frame(true, 200, 200);

results in dmesg:
     gnome-shell[21505]: segfault at 28 ip 00007f9681c32e67 sp 
00007ffff2263b50 error 4 in libmutter.so.0.0.0[7f9681bcc000+b7000]

resize and move works as expected.

System: Ubuntu 12.04
Shell: 3.4.1
Mutter: 3.4.1

cheers
