GTKPOD unable to open M4A files

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):
Steps to Reproduce:
1. In gtkpod with an ipod loaded, click 'add files' or 'add folder'
2. Make selection to include .m4a files
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'
Successfully adding the file to my ipod as it did in the (uncertain but not-too-distant) past.
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
I helped someone in #gtkpod debug this the other day. It seems that the libmp4v2 in F-11 cannot parse most .mp4/.m4a files. I used mp4info on a file that gtkpod failed to read and it failed to read it as well. The same files parse fine with gtkpod and mp4info on F-10.
Any ideas what changed in libmp4v2? It seems like a pretty big problem for libmp4v2 to not be able to read mp4 files...
I think the problem was due to a bad libmp4v2 build. It might have been built at a time when gcc or some other component of the tree was a bit flaky. There is an updated libmp4v2 available (libmp4v2-22.214.171.124-9.fc11) which fixes this issue. This was apparently reported in bug #507302.
I've verified that the update fixes mp4info. I did not test it with gtkpod, but I fully expect it to work. If it does not, please reopen this bug.
