A file which gtkpod cannot open

Description of problem:
Gtkpod gives an error when trying to add .m4a files that it previously accepted.

Version-Release number of selected component (if applicable):
0.99.14-2.fc11

How reproducible:
Always

Steps to Reproduce:
1. In gtkpod with an ipod loaded, click 'add files' or 'add folder'
2. Make selection to include .m4a files
  
Actual results:
Error dialog opens, with two messages:
- Could not open '/path/to/file.m4a' for reading, or file is not an mp4 file.
- The following track could not be processed (filetype is known but analysis failed): '/path/to/file.m4a'

Expected results:
Successfully adding the file to my ipod as it did in the (uncertain but not-too-distant) past.

Additional info:
The files in question were encoded by iTunes 7 for Mac OS and have worked previously with gtkpod and continue to be playable. A sample can be uploaded if needed
