That should not have had any effect on this bug.

The problem is _where_ you do the checkout, not _what_ you checkout.

So please try to reproduce this.

I use mtn on windows a lot, and it definitely can't operate in the
root directory of a drive. That's never a problem in real life, so I
haven't tried to fix it.
