I looked at Christophe's machine that has the same problem. He was also 
running Ubuntu 11.04 on classic mode. It looks like the problem might be 
in compiz with this particular configuration. When I disabled the 
"detection" extension on ccsm, compiz restarted and weston started to 
run fine. The problem returned after a log out/log in cycle. The 
extension was disable and turning it back on fixed the problem again. So 
it seems the reset caused by ccsm that actually fixed the issues. Since 
the problem seems to be in compiz, I stopped debugging.

Hope that information helps.
