Here's the bug: some code thinks that "C:/foo" is not an absolute file
name, probably because it checks for the leading slash.  So it
prepends a slash, which alters the semantics of the file to be a
remote file on a mythical machine called "C", with predictable
results.

I'd take a good look at vc-bzr-working-revision and the subroutines it
calls.
