I understand that this fails, and that you expect this to work. However
as far as I'm aware there's no design of git-ubuntu possible where this
will work in all edge cases, so this is an unfortunate interaction and
not a bug in git-ubuntu or the imported qemu package.

Where this edge case applies, correct. I don't know how to make this
possible in the general case. git won't let us (and it doesn't make
sense to) have an imported source package contain a .git directory. If
the build requires that, then it's not going to work.

The closest we can get is to this is to escape the .git in a way that
can be undone before calling dpkg-buildpackage, and that's already done
and working as expected. If you want some code to do the unescaping,
that's available in the git-ubuntu source.

Until "git ubuntu build" is fully implemented, you need to rename ..git
to .git before your build step if you want this to work.
