Comment 0 for bug 711422

This message popped up after the latest update of 11.04. I could not start the Desktop Edition and was only presented a blank screen with my wallpaper. Then, after loading the Classic Edition with no effects apport popped up and I reported the issue.

Sorry for the terrible bug title, but I could not translate this cryptic message to anything meaningful.
