[bzrtools] exception thrown when using baz-import

[Jamie Wilkinson]

Hey,

I'm trying to import some old baz archives into bzr, using the shiniest
latest bzrtools from http://panoramicfeedback.com/opensource/bzr/bzrtools,
and pybaz from ddaa at ddaa.net--2004/pybaz--devo--0--patch-148 , and I'm
getting this error:

dawn% bzr baz-import ~/src/bzr-from-baz jaq at spacepants.org--2004
importing jaq at spacepants.org--2004/almanac--proto--0 into
/home/jaq/src/bzr-from-baz/almanac/proto
Cleaning up
bzr: ERROR: exceptions.TypeError: name must be a str, but was:
bzrlib.plugins.bzrtools.pybaz.Revision('jaq at spacepants.org--2004/almanac--proto--0--base-0')
  at /home/jaq/src/barry/pybaz/pybaz/_builtin.py line 83
  in _check_param_type

Is there a newer pybaz that baz-import is supposed to work with?
