Was this repository perhaps earlier checked out with older versions of
bzr-svn? If so, you might want to remove your existing caches in
~/.cache/bazaar/svn/ or ~/.bazaar/svn-cache.

So far this error has always been caused by the fact that older versions
of bzr-svn would leave a half-filled cache when they were interrupted,
leading to errors such as this one later.

I can confirm that it is possible to check this branch out from scratch
without problems.

Cheers,
