The "unknown error" thing happens when gnc-fq-helper returns results that parse-quotes.scm can't parse into a list. To
troubleshoot further, go through *all* of your securities and disable quote retrieval on all but one of them. Try to get quotes. If it works, turn quote retrieval back on for one more security and try again. Lather, rinse, repeat until it fails, then feed the last one added to gnc-fq-helper like this:
  echo '(yahoo "BP.L")' | gnc-fq-helper
and see what you get back. If everything's working right it should be something like
(("BP.L" (symbol . "BP.L") (gnc:time-no-zone . "2016-10-07 17:10:00") (last . 4.86) (currency . "GBP")))
Since it's failing, it probably won't look like that, and the output will probably be a good clue as to what's going wrong.
