listener failing after first program start

[bmeyer71]

Not sure why I am getting the following error:

2017-07-21 11:25:06,329 DEBG ordered_startup: ACKNOWLEDGED -> UNKNOWN
2017-07-21 11:25:06,329 WARN ordered_startup: has entered the UNKNOWN state and will no longer receive events, this usually indicates the process violated the eventlistener protocol

As far as I can see things are setup correctly.

As a side note, I did have to add the following to the script to get it to work:

#!/usr/local/bin/python2.7

if __name__== "__main__":
    main()

I know I could have specified it as a commandline option to python, but this makes it easier.

Any ideas what I might be missing or what is wrong?

interestingly, I tried the fork by @flixr and that one works for me. I haven't had time to see what the difference is though.
