This problem exists for me in Intrepid as well. I am up-to-date as of 30 Sept. A secondary issue (that I will report in a separate bug) is that the gnome-power-manager icon does not reflect that I am currently plugged in. That is not always the case, but is so now. Taking a cue from pinguino I'll report some system information below:
