beryl crashes randomly

Binary package hint: beryl-core

I start Beryl-manager manually with the run command. It won't launch from the menu. Then it randomly crashes. Sometimes quickly after logging in, sometimes after a while - there is no pattern. It doesn't matter what application I'm running either. Ctrl-Alt-Backspace gets me back to KDM to re-login.
