This exact bug also happen when trying to upgrade a chroot with a full and unmodified squeeze desktop to wheezy. From the test log:

Searching for "Could not perform immediate configuration on 'phonon-backend-vlc'" on the web show several users see the same problem. I even found a Ubuntu bug report from February detecting the same issue, <URL: https://bugs.launchpad.net/bugs/911659 >, but it apparently went away without anyone knowing why. Perhaps this bug is in apt, given that some reports that it help to upgrade apt first? -- Happy hacking Petter Reinholdtsen -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
