I can see the immediate cause of this.
The actual sequence is link.rm, common.mkdir,
link.rm, common.mkdir, but common.mkdir is checked
for uniqueness, so the second mkdir is dropped.
Unfortunately, I'm not sure how we got here
in the first place, since we shouldn't be processing
this directory twice at all.

I can't reproduce this myself.
Can you try applying the attached
patch which adds additional debug
output and report the result?
What I suspect is that the paths
are not properly normalized before
comparison.
