AssertError: Empty parent added, but child wasn't added

[Christoph Neumann]

I'm running bzr-svn 0.5 trunk revno 2271

bzr branch -v http://server/svn/test/project/trunk project
cd project
bzr svn-push -v http://server/svn/test/project/branches/foo

I get an assert error:

bzr: ERROR: exceptions.AssertionError: Empty parent 'project/branches' added, but child 'project/branches/foo' wasn't added !?

I found the problem. I had recreated the subversion repo from scratch, but I had not removed ~/.bazaar/svn-cache. After clearing the cache, the svn-push worked just fine.
