The download method raises an http500 error

[GoogleCodeExporter]

What steps will reproduce the problem?
1. locate the id to a downloadable item (voicemail or recorded call)
2. call download on an instantiated Google Voice object, passing it the id

What is the expected output? What do you see instead?
I expect a file to be downloaded. Instead I get a DownloadError

What version of the product are you using? On what operating system?
hg tip, Windows 7

Please provide any additional information below.

I'm not sure if something has been changed on google's side or what, but as of 
approximately three days ago download consistently raises an http 500 error, 
well, specifically a DownloadError which I have determined is being caused by 
an http 500.

Running under CentOS (system running Asterisk) I have tried several different 
ways to download voicemails and must concur with the OP - something appears to 
be broken. I even ran the downloaded example code (python download-mp3.py) 
after making the file executable, and still no joy - instead I received the 
following error:

Traceback (most recent call last):
  File "download-mp3.py", line 9, in ?
    message.download(download_dir)
AttributeError: 'unicode' object has no attribute 'download'
