Yes. I added you to the cc exactly because it was hard for me to judge
from the email discussion that is linked to in the regression list whether
you actually _did_ mark some versions good because of confusion about the
version numbering.

That would certainly explain why bisection didn't seem to work.

But it's not the _only_ reason bisection doesn't work. Sometimes you can
be as careful as possible, but if it's a bug that is even _slightly_ flaky
(timing-dependencies etc), and the bisection marked something good that
shouldn't have been (or vice versa, but that's unusual), then the
bisection end result won't be right.

So you may well have done everything right, and I'm not trying to blame
you. I just was hoping that maybe that confusion would explain why the
bisection didn't seem to pinpoint anything sane..

It would be good, especially if this bug doesn't end up being solved some
other way... And slow results are better than no results at all ;)
