Comment 3 for bug 466661

I saw the other bug. It was non-reproducible and in Xubuntu; mine is reproducible (although through an unusual series of events which I described in the initial post) and in the released Karmic 64bit desktop livecd. The backtrace may be the same, but since it is a violated assertion I assumed that the real bug was in the surroundings, i.e. whatever other program didn't supply what was asserted here to be required.
