Decode Error in asf.py on Open

[GoogleCodeExporter]

Python: 2.7 x64
Platform: Windows 7 x64

Hi,

I have a small (but significant) number of WMA files that are failing to open 
in Mutagen.

Below is the exact error, as thrown. I use Mutagen to query file runtimes. I 
suspect there may be something in a Metadata tag somewhere, but I have 
'cleared' all tags using Windows 7 built-in option.

I am happy to send a copy of an offending file, I just didn't want to attach it 
publicly.

Kind regards,

Geoff

Error is as follows:

One UTF-16 value is null terminated in the middle of the value.
