--whitespace causes decoding to fail under Windows

[J K.Eason]

I always used to use the '--whitespace' or '-w' command line flag to
download radio programs under Windows so that I didn't need to remove the
underscores from the filenames. Something changed a couple of months ago
(possibly when the BBC dropped the iPhone file format?) because
get_iplayer now always fails after the download completes, both with
radio and TV. This happens whether I use RTMPDump or flvstreamer.
 
Here's a failed attempt:
