update-manager crashed with TypeError in confirmChanges(): glib.markup_escape_text() takes at most 1 argument (2 given)

[Ian Sharum]

I had inadvertently left Ubuntu 11.10 Beta 1 running while i was at work, when i came home approximately 11 hours later i noticed the computer was on and was proceeding to shut it down. When I moved the mouse to wake the screen, i noticed an error message saying that not all updates could be installed and that i needed to run a partial upgrade. I told it to run, it started to calculate changes and then after a short time the partial upgrade window disappeared and the error report box appeared asking me to report a problem for a system program.
