gtk-window-decorator crashes several times a day. backtrace.

Binary package hint: compiz

2-3 times a day, all my window borders disappear.
I've learned what this is, and after the first time run gtk-window-decorator manually from a shell, inside gdb. While this results in a deadlock when it crashes a second time, I do get a stack trace. Here's the most typical backtrace:
