This is nothing to do with gnome3/window manager. We did test with plain 
X and got the same system freeze. This is something to do with the low 
level xlib calls (Xorg or video driver/kernel ). We also tested running 
rdesktop from a different machine setting the DISPLAY to the machine in 
problem, we faced the same issue. So this confirms the problem is with 
the X.
