compiz crashed with SIGSEGV in PrivateWindow::processMap()

[Jasper Westpfahl]

Binary package hint: compiz

I started matlab 2010a and compiz crashes and takes all upper most bars from all the windows, the minimize maximize and close buttons disappear. They come back after a moment. When I close Matlab and start it again compiz does not crash.
The issue seems to be getting better with every update.
