[Bug 945400] [NEW] compiz crashed with SIGSEGV in DecorWindow::updateFrame()


You have been subscribed to a public bug:

Compiz crashed when I disabled "Snapping Windows" while enabling "Wobbly
Windows". However, after CCSM was restarted or relaunched Wobbly effect
is working.

(I don't know if this is a "security vulnerablity", anyways I have
reported this as such.
