The virus scanner is the most likely culprit - many virus scanners
implicitly lock the file they are scanning, and bzr tries to rename
the file while its locked, which fails.
If you could try doing a branch with the scanner actually disabled,
(turn 'on-demand' or 'on-access' scanning off), I suspect it will
work. If that works, file a bug with mcafee :)
We might be able to work around it, but its going to be ugly.
