Errors when testing with httprint

[mzfr]

I was testing httprint on Snare for issue #7.

$ sudo python3 snare.py --port 8080 --page-dir example.com

This occurred when I ran this command on httprint: httprint -h 127.0.0.1:8080 -s signatures.txt -P0

The dorks.pop issue is occurring here because the dorks list is empty.

Even though there is a check to deal with the empty case, it won't work if the request times out as it did in this case.

Thanks for the issue. Would you like to fix it?

This is actually tanner's issue
