Push to Subversion after tag in Bazaar fails

[Russel Winder]

I used "bzr tag 1.4.0" on a Bazaar branch whose parent is a Subversion repository, this worked. I then tried pushing the branch and:

|> bzr push
Using saved location: svn+https://svn.codehaus.org/gant/gant/trunk
The svn+ syntax is deprecated, use https://svn.codehaus.org/gant/gant/trunk instead.
using experimental bzr-svn mappings; output may change between revisions
bzr: ERROR: exceptions.NotImplementedError:

This bug occurs in a version of bzr-svn that's not in ubuntu.
