X crashes when keeping tab pressed using Compiz Shift switcher

[Master]

Binary package hint: compiz

When I keep Tab pressed or use the left and right arrows in the Shift Switcher:

The X server crashes and restarts, and I get back to the login screen. For a quarter of a second when X restarts, I can see the last desktop with the applications on the screen. But all my session is lost.

It happens only with this effect: everything ok with the cube, even if keeping the arrow pressed and making turning the cube for dozens of seconds.
