I'm getting an error when generating the documentation on Mac OS X 10.6:
 
python tools/generate_docs.py -o doc/en/user-reference/index.txt rstx
Traceback (most recent call last):
  File "tools/generate_docs.py", line 106, in <module>
    main(sys.argv)
  File "tools/generate_docs.py", line 93, in main
    infogen_mod.infogen(options, outfile)
  File "bzrlib/doc_generate/autodoc_rstx.py", line 56, in infogen
    outfile.write(_get_body(params, topic_dir))
  File "bzrlib/doc_generate/autodoc_rstx.py", line 69, in _get_body
    result.append(_get_commands_section(registry, output_dir=topic_dir))

    i18n.install()  # Install i18n only for get_help_text for now.
  File

    languages=lang.split(':'),
AttributeError: 'NoneType' object has no attribute 'split'
make: *** [doc/en/user-reference/index.txt] Error 1
 
I was able to workaround it by setting LANG=en in my shell before
running the build, but I've never had to do that before.
 
I think it would be a reasonable assumption for _get_current_locale() in
bzrlib.i18n to assume 'en' if it cannot find any other locale information.
 
Ciao,
Gordon
