Minor Description
This is minor - but it's a little unclean 
Reproduce: Have a URL-file with one URL followed by a newline, thus producing an empty line.
Outcome: Fetcher-threads try to fetch two URLs at the same time. First one is fine - but second is empty and therefor fails proper protocol-detection.
