To reproduce:

Create a link, say to /tmp:

  bagira:~/python> ls -l xxx
  lrwxrwxrwx    1 ilya     ilya            4 2005-06-02
17:09 xxx -> /tmp/

And now:
 
  bagira:~/python> python2.4
  Python 2.4.1 (#2, May  5 2005, 11:32:06) 
  [GCC 3.3.5 (Debian 1:3.3.5-12)] on linux2
  Type "help", "copyright", "credits" or "license" for
more    
   information.
   >>> import os.path
   >>> os.path.realpath("xxx")
   '/home/ilya/python/xxx'

I'd expect realpath() to return "/tmp"

Confirmed. Only occurs when the symlink is the first
directory part of the argument. Attaching fix, assigning to
Raymond to check in.

Be sure to add an entry to Misc/NEWS.
