If config.yaml has bad format, sd2 daemon process dies without any message

[theronfff]

I created a config.yaml that had a tab character in it, which the yaml parser doesn't like:

yaml.scanner.ScannerError: while scanning for the next token
found character '\t' that cannot start any token
  in "<unicode string>", line 37, column 1:
    	enabled: true
    ^

When I saved this file, the sd2 daemon process immediately died. The only in the logs that I could find was this:

2018-09-20 14:42:35 44097 INFO     SD2INIT:EE

It was only by running sd2 again that I found out what the problem was.
