Do you onyl have compiz in experimental? Or also some other X packages?
Which xserver-xorg-core do you have? The following backtrace seems to
end up in xserver-xorg-core, you could try this package in experimental

How did you get this backtrace? It does not look like a complete
backtrace with debugging information that gdb could give.
