I've also ran into this under the same circumstances (with an svn  
add'ed directory), however it manifested on line 224:

   File "/usr/local/lib/python2.4/site-packages/setuptools-0.6c6- 
py2.4.egg/setuptools/command/egg_info.py", line 179, in tags
     ):  version += '-r%s' % self.get_svn_revision()
   File "/usr/local/lib/python2.4/site-packages/setuptools-0.6c6- 
py2.4.egg/setuptools/command/egg_info.py", line 224, in get_svn_revision
     localrev = max([int(d[9]) for d in data if len(d)>9 and d[9]])
ValueError: max() arg is an empty sequence
