bzr-fastimport-0.13.0 incompatible with bzr-2.5.1

[Tassilo Horn]

Hi all,

I'm trying to convert a CVS repository to bazaar.  Therefore, I used
cvs2bzr [fn:1] to create a dumpfile that I can fast-import.  However,
that gives the following error:

--8<---------------cut here---------------start------------->8---
% bzr fast-import ../cvs2svn-tmp/dumpfile.fi auctex.bzr
bzr: warning: unsupported locale setting
  bzr could not set the application locale.
  Although this should be no problem for bzr itself, it might
  cause problems with some plugins. To investigate the issue,
  look at the output of the locale(1p) tool.
bzr: ERROR: exceptions.ImportError: cannot import name error

*** 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.

Indeed, when checking the bzr-2.5 branch I can see that bzrlib.trace
does not contain a function `error'.  So are bzr-2.5.1 and
bzr-fastimport-0.13.0 incompatible to each other?

Bye,
Tassilo
