Bad mime type reported for flac file

Hi all,

It has recently come to my attention that the linux "file" utility  
reports some (but not all) of my flac files as having a mime type of  
"audio/mpeg".  Obviously this is incorrect, but why is it reported as  
such?  I've cut and paste a few commands below from my shell to  
illustrate what I'm seeing:

black:/media/mildred/music/Tool/10,000 Days$ file -i *
01-Vicarious-10,000 Days-Tool.flac:                  audio/mpeg
02-Jambi-10,000 Days-Tool.flac:                      audio/mpeg
03-Wings For Marie (Part 1)-10,000 Days-Tool.flac:   audio/mpeg
04-10,000 Days (Wings Part 2)-10,000 Days-Tool.flac: audio/mpeg
05-The Pot-10,000 Days-Tool.flac:                    audio/mpeg
06-Lipan Conjuring-10,000 Days-Tool.flac:            audio/mpeg
07-Lost Keys (Blame Hofmann)-10,000 Days-Tool.flac:  audio/mpeg
08-Rosetta Stoned-10,000 Days-Tool.flac:             audio/mpeg
09-Intension-10,000 Days-Tool.flac:                  audio/mpeg
10-Right In Two-10,000 Days-Tool.flac:               audio/mpeg
11-Viginti Tres-10,000 Days-Tool.flac:               audio/mpeg

black:/media/mildred/music/Tool/10,000 Days$ metaflac --export-tags- 
to=- 01-Vicarious-10\,000\ Days-Tool.flac
ARTIST=Tool
TRACKNUMBER=01
ALBUM_ARTIST=Tool
ALBUM=10,000 Days
TITLE=Vicarious

black:/media/mildred/music/Tool/10,000 Days$ flac -dc --totally-silent  
01-Vicarious-10\,000\ Days-Tool.flac | flac --totally-silent -eo  
Vicarious_test.flac - ; file -bi Vicarious_test.flac
audio/x-flac

black:/media/mildred/music/Tool/10,000 Days$ metaflac --show-md5sum 01- 
Vicarious-10\,000\ Days-Tool.flac Vicarious_test.flac
01-Vicarious-10,000 Days-Tool.flac: 9269f0bbc4c4a8f48d72f0e380277206
Vicarious_test.flac:                9269f0bbc4c4a8f48d72f0e380277206

This led me to wonder if it was the tags..?  Since in theory both flac  
files are the same..?

black:/media/mildred/music/Tool/10,000 Days$ metaflac --remove-all- 
tags 01-Vicarious-10\,000\ Days-Tool.flac
black:/media/mildred/music/Tool/10,000 Days$ file -ib 01-Vicarious-10\, 
000\ Days-Tool.flac
audio/mpeg

No go...  This is strange yes?  I can write a script to convert them  
all, transfer all the tags, etc, but, I'm still curious as to why this  
is happening.  If anyone has any ideas, I'd love to hear them.

Oh, and for the record books:

Ubuntu 8.04.1 LTS

black:/media/mildred/music/Tool/10,000 Days$ file -v
file-4.21
magic file from /etc/magic:/usr/share/file/magic

black:/media/mildred/music/Tool/10,000 Days$ uname -a
Linux black 2.6.24-18-server #1 SMP Wed May 28 21:25:52 UTC 2008 i686

black:/media/mildred/music/Tool/10,000 Days$ metaflac --version
metaflac 1.2.1

black:/media/mildred/music/Tool/10,000 Days$ flac --version

Thanks,
