While dragging the window, X has mouse capture, so this hangs your
session when the error happens.

To break the capture, (quite useful when debugging GDK (and X) apps 
on Linux): Ctrt-Alt-NumDiv (hit at the same time). If your X server
is set up to accept this, it releases the mouse capture. 

You might have to enable this in your xorg.conf file (something like 
DeactivateGrabs should be set).
