I haven't used logging config files, but I don't see anything obviously 
wrong here. A couple of ideas to try:
- make sure logging.conf can be found by
   print os.path.exists('logging.conf')
- turn on console logging in the config file and see if that works
- try to configure the syslog handler in code instead of in a file, then 
translate the successful configuration to a file.
