I'm glad people agree it is indeed a bug and should be reported.
Please note that I was only describing the bug in passing.  The subject
of the thread is that  I cannot submit a bug report.

It opens a blank browser window after the first question, and then
ends (I get a prompt back from ubuntu-bug in the shell window.)

I also cannot submit a bug about my inability to submit a bug for
obvious reasons.
