Funny enough, but PayPal’s Facebook action to gather "Like"s and get information on users has a bug when you select not to accept providing them all information (yes, that is too much to my understanding, giving a "Like" may have been OK):
System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. at System.ThrowHelper.ThrowKeyNotFoundException() at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at Facebook.JsonObject.get_Item(String key) at EnterContest.Page_Load(Object sender, EventArgs e) in d:\var\httpd\PayPal-Benelux\htdocs\default\www\facebookactie\EnterContest.aspx.cs:line 41
PayPal, you could have done better!
Happy New Year to everybody!
