I have the same problem on my machine. `bzr info` works while `bzr info -v` does not.

*** Bazaar has encountered an internal error.  This probably indicates a
    bug in Bazaar.  You can help us fix it by filing a bug report at
        https://bugs.launchpad.net/bzr/+filebug
    including this traceback and a description of the problem.

This is with bzr 2.0.3

I can provide entire archive of my repo for your experiments if you want (this is from scmproj project).
