CentOS - Mar 2006 - file command returns incorrect MIME type?

Here's the problem: 

[ben at kepler tmp]# file -i presentation.ppt
presentation.ppt: application/msword

I see lots of references to this problem, (EG: IMP, PHP bug, etc) all of which 
conclude, in various forms, "the problem is in your /usr/share/magic.mime,
go
away". But nowhere (that I've been able to find) is there actually a
solution
- and even the magic.mime file from the latest tar (downloaded from 
astron.com) didn't fix it, either. The magic file in the apache directory 
seems to come up with the answer of: no answer. When you access a ppt in 
apache, it comes back with a generic response rather than 
"application/powerpoint" 

Any ideas?

Excerpt from /usr/share/magic.mime:

--- snip ---
# msword: file(1) magic for MS Word files
#
# Contributor claims:
# Reversed-engineered MS Word magic numbers
#

0	string		\376\067\0\043			application/msword
0	string		\320\317\021\340\241\261	application/msword
0	string		\333\245-\0\0\0			application/msword
--- snip ---

The middle one of those matches the first six bytes of a powerpoint
file.  Whether it also might match the first six bytes of some msword
documents, I don't know.
