I run into nulls occasionally. Not sure if they are older WC's that
have been upgraded to new formats but I've hard to guard against it in
Subclipse. Same with the repository root URL.

I cannot recreate this, but I swear in the past I've seen this with
in-place imports. Basically checkout project root, add
trunk/tags/branches and commit. Then add stuff to trunk and commit
etc. None of the stuff has the UUID set in the WC. Like I said, I do
not think I can recreate it now though.
