Curl error (errno: 3, error: malformed url)

I am new to curl. Does anyone know if there is a particular reason I would get a malformed url error with the following url:

http://atlanta.craigslist.org/search/sys?query=lcd&catAbbreviation=sys&minAsk=min&maxAsk=max

Try & instead of &

still get the same error…

Add:
var_dump(curl_getinfo($ch));
see: http://at.php.net/manual/en/function.curl-getinfo.php
How does ‘url’ look like?
