compiz crashed with SIGSEGV in PluginClassHandler<DecorWindow, CompWindow, 0>::get()

[afoglia]

Binary package hint: compiz

Another crash while enabling/disabling the switchers. This time I was able to unselect the Static Application Switch, and enable the Application Switcher. But when I tried to undo my changes, again compiz crashed.
