*** This bug is a duplicate of bug 54163 *** Thanks for your report. I'm going to treat this as a duplicate of bug 54163, which I'll soon have fixed in Edgy. I believe that the workaround is to avoid hitting the back and/or next buttons more than once in quick succession; although just in case that wasn't it, I'll add a little more insurance code.
