Comment(by dd32):

 An array of headers will be returned in the event that a header is
 duplicated in the response.

 There was a bug in 2.9 with Fopen and redirects (or proxies) which would
 result in multiple headers being returned which could cause this.

 There's a bug i just noticed in the array returning however if there are
 >2 items of any of the headers in there..

 The code in question here, in the RSS code, probably needs to be updated
 to only return a String. Some docs may need to be updated to reflect the
 array returning of the function as well..
