The curl_easy_escape function will escape the *entire* string, so you end
up with a string like
http%3A%2F%2Fspotlight.dbpedia.org%2Frest%2Fspot%2F%3Ftext%3DPresident%20Obama%20called%20Wednesday%20on%20Congress%20to%20extend%20a%20tax%20break%26spotter%3DLingPipeSpotter
which isn't a URL at all. You should really check the return code of all these
functions to find out where libcurl doesn't like the input.
