I think this sounds like it could still be a common bug to both mutter and kwin so let's keep that open. Certainly the circumstances agree with the error message and it sounds logical to me that the compositor could be to blame.

I saw the crash occur after a screensaver had been running, and the screens had gone blank. I assume this means they were turned off by the sleep timer. When I worke the machine, I was presented with a prompt, I *quickly* entered my login credentials and momentarily saw the desktop and all open programs on it. Then, the screens (3) flickered and I saw the login prompt again. I logged in (again), and all applications had been shut down. I checked /var/log/syslog and saw the following details -- see (log). Uploaded file, and the crashdump.
