ubiquity crashed with AttributeError in reset_locale()

[DavidWells59]

Binary package hint: ubiquity

Nautilus main screen did enable me to move files around but now for some reason it is stuck, or if you like another word, "frozen"!
I don't konw how to get it "unstuck" or "un-frozen" and clear the screen even thought i've tried a number of things. It sure mesesses up what other things I want to do, even though I can get around it by going to another entirely different screen altogether.
