ID3 writeback fails (Invalid Language in COMM)

I'm trying to use the new Edit Media mode in 1.0b17.  All my MP3s were
encoded with ID3v2 tags using Grip/Lame.  If I try to change the Track
Name in Netjuke, when I save, it says:

Invalid Language in COMM ( )
GenerateID3v2FrameData() failed for "COMM"
Error generated in getID3() v1.6.1
GenerateID3v2Tag() failed

Looking at the MP3, there doesn't appear to be a language in the COMM
field.  Is this legal?  Is there a bug in getid3, or is it a bug in Lame?

Thanks,
Matt
