Comment (by toralf):

 FWIW calling python2 instead of 3 gives :
 {{{
 ms-magpie ~ #  /home/tfoerste/info.py
 ['proc', 'netstat', 'lsof', 'ss'] : proc
 Traceback (most recent call last):
   File "/home/tfoerste/info.py", line 162, in <module>
     main()
   File "/home/tfoerste/info.py", line 123, in main
     if policy.can_exit_to(raddr, rport):
   File "/usr/lib64/python2.7/site-packages/stem/util/lru_cache.py", line

     result = user_function(*args, **kwds)
   File "/usr/lib64/python2.7/site-packages/stem/exit_policy.py", line 286,
 in can_exit_to
     if rule.is_match(address, port, strict):
   File "/usr/lib64/python2.7/site-packages/stem/exit_policy.py", line 755,
 in is_match
     raise ValueError("'%s' isn't a valid port" % port)
 ValueError: '0' isn't a valid port
