Problem with latest tags code

[Russel Winder]

Using bzr.dev up-to-date working from the tree with bzr-svn from http://people.samba.org/bzr/jelmer/bzr-svn/0.4 at revision 1436, when I try to create a new branch of the Gant Subversion repository, I get the following error. This leads to the repository for the branch being created but no working tree. bzr checkout gets the working tree. However any attempt to pull leads to the same error as below. bzr missing indicates the branches are the same.

|> bzr branch svn+https://svn.codehaus.org/gant/gant/trunk Trunk
using experimental bzr-svn mappings; output may change between revisions
