Hmm, thats a good start.  So now you know a GOOD revision, and a BAD
revision.  Now, go and read "man git-bisect", don't be afraid, it is
actually not complicated.  git bisect is a binary search mechanism for a
revision control system.  Given a GOOD and BAD revision, it will
checkout a revision between them, and let you perform a test such that
you can tell it if this revision is good or bad.  If you repeat this
step a few times (not often), the binary search will narrow down to the
actual change which introduced the problem.

It helps to know that apparently, it is really a software problem.  We
should narrow it down and fix it.
