I had a problem upgrading to the beta a few weeks ago. I had some conflicting/broken packages and the installation couldn't finish. It seems the WM crashed and I was unable to access a terminal until I remembered I could switch to a tty. Ran `apt-get -f install` and fixed everything. Haven't had an issue on the official release yet though.
