Unhandled error: ('The VCC property was not found on the resource', 20014)

Howdy all,

I'm getting a rather strange message trying to branch from a public
branch to a local one:

=====
bzr> version
Bazaar (bzr) 1.3.1
  Python interpreter: /usr/bin/python 2.5.2.final.0

The same happens if I try this outside a shared repository, so
presumably that doesn't have any bearing on it.

What can I do to troubleshoot this further?
