querystring parse has bug

I've noticed some url's coming in from google that have the parameter aq=t and also a q=some+search ... the first aq=t gets parsed by the Search Keywords module as the query, not the second q=. I'm assuming the match is on q= when it should be on &q=? Just noticing many log entries for q=t ... but the url is actually contains aq=t. Thanks for the cool module, works well otherwise. I can submit a patch if you don't have time, just let me know.
