I have come across a few tweets that have a URL mentioned in the text but the URL entity is empty. See below:
{
"created_at": "Thu May 05 11:47:03 +0000 2011",
"id": 66106631431262208,
"id_str": "66106631431262208",
"text": "Chic French brand, The Kooples, is now open on First Floor in The Village. See their look book here http://on.fb.me/jSjmvd",

"entities": {
"hashtags": [],
"symbols": [],
"urls": [],
"user_mentions": []
},
"favorited": false,
"retweeted": false,
"lang": "en"
}
Under what circumstances is this entity populated?
