My guess is that this will work fine with bzr 1.5 and that
bzr-fastimport needs to be updated to support a newer API in
bzr 1.6. I'll look into that now.

This looks like Mercurial has changed their API since hgimport was
written.

Right now, use bzr-fastimport with bzr 1.5. Once you've generated
the bzr repository, you can use 1.6b3 again. I'll take a look at fixing
bzr-fastimport to support both the older and newer bzrlib API. I'll
let you know when that's done.
