Loggerhead crashes on start: bzr: ERROR: exceptions.TypeError: serve_http() takes at most 4 arguments (5 given)

[Dario D'Amico]

I originally filed a bug report for Bazaar (bug #1070443 for Bazaar, NOT Loggerhead)
because the error message instructed me to do so, but since it could be a Loggerhead
bug and there haven't been new releases of these two softwares since then, I'm posting it
again, unchanged, as a Loggerhead bug.

----- Original text follows -----

I try to serve on Mac OS X 10.7.4 using the following command:

$ bzr serve --http

This results in the following error:

bzr: ERROR: exceptions.TypeError: serve_http() takes at most 4 arguments (5 given)

*** 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.

My Bazaar version is Bazaar-2.6b2-OSX-10.6-1.dmg and I'm not sure why I got this version since it is not listed here:

http://wiki.bazaar.canonical.com/MacOSXDownloads

But it is listed here:

I installed Loggerhead on 23 October at 18:10 CEST 2012 by going in my plugin directory and typing:

bzr branch lp:loggerhead

I also tried to run the setup:

$ python setup.py build_ext -i

But I get an error:

Traceback (most recent call last):
  File "setup.py", line 23, in <module>
    import loggerhead
  File "/Users/Dario/.bazaar/plugins/loggerhead/loggerhead/__init__.py", line 29, in <module>

The same error occurs with loggerhead-1.18.1.tar.gz, either with the command above or with make.
