Problem parsing HTTP headers

[asieira]

I'm using httr 0.6.0 and RCurl 1.95-4.5 and it is mishandling the contents of the last-modified and date headers as this simple test can demonstrate:

> str(HEAD("http://s3.amazonaws.com/alexa-static/top-1m.csv.zip")$header)
List of 9
 $ x-amz-id-2                           : chr "GkWR2aH+lx0jARitIcfDMBRMXKEjBxvUqslK6WSPPNsB+XdC3rYKtO7ENJTaRqWbNn4gHFgcI0s="
 $ x-amz-request-id                     : chr "BFE21FB42A076BDB"
 $ date: wed, 17 dec 2014 18:39         : chr "59 GMT"
 $ last-modified: mon, 15 dec 2014 23:01: chr "07 GMT"
 $ etag                                 : chr "\"8bef9f727c803d2b09e80b44638cfe71\""
 $ accept-ranges                        : chr "bytes"
 $ content-type                         : chr "application/zip"
 $ content-length                       : chr "10126559"
 $ server                               : chr "AmazonS3"
