Just as an FYI for anyone who runs into a similar problem, the solution is basically the same, but the cause of the problem isn't obvious.

After upgrading Debian wheezy, mysql failed to start.

Somehow, I have no idea how, permissions on some of the files in /var/lib/mysql were not owned by the mysql user, thus preventing the server from firing up.

A chown -R mysql.mysql /var/lib/mysql fixed it.

I didn't do anything to mess up mysql, it was a standard:

apt-get update

apt-get upgrade

Something got hinky during the Debian upgrade and manual intervention was needed.
