Comment 1 for bug 310310

Thanks for the report; I think this is failing because bzr-hg is out of date with bzr.dev.

_fallback_repositories is defined in Repository.__init__ and so should be expected to be provided by subclasses. Possibly it should be in the ForeignRepository base and bzr-hg should use that.

To work around this problem you can: add this line

 _fallback_repositories = []

into the Repository subclass in bzr-hg.
