Comment 4 for bug 361674

OK, I can apparently reproduce at will on VirtualBox, it seems
to rely on selecting French at gfxboot time, selecting French
on the first page of ubiquity doesn't trigger it. davmor2 also
confirms that this is not just VirtualBox.

The traceback may be a red herring, checking the debug log
while ubiquity is hanging shows nothing of interest, only
quitting ubiquity shows the traceback. Either it is the
program being torn down that causes the backtrace, or it
is hanging in sys.excepthook. What would be the best way
to determine that?

Thanks,

James
