Description Jan "Yenya" Kasprzak 2007-11-24 16:01:05 EST
Description of problem:
After upgrading to F8 the detection of MIME types using shared-mime-info (and
perl-File-MimeInfo) does not work as expected anymore. All MS Office documents
are detected as Powerpoint.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. install perl-File-MimeInfo package
2. save a MS-Word document as (say) /tmp/aaa (do not use any file extension so
that the extension-based heuristics of perl-File-MimeInfo do not trigger).
3. $ file -i /tmp/aaa
4. $ perl -MFile::MimeInfo::Magic -e 'print mimetype("/tmp/aaa"), "\n"'
Actual results:
file(1) detects the contents correctly as application/msword, while Perl prints
application/vnd.ms-powerpoint instead.

Expected results:
application/msword for both cases.

Additional info:
After downgrade to shared-mime-info-0.20-2.fc7, Perl prints
"application/x-ole-storage", which I consider better than what F8 does, because
it at least tells me "try to use some heuristics based on the file name
instead". This downgrade also tells me that the problem is in shared-mime-info,
not in perl-File-MimeInfo.

Could you please attach the file you created? "Save a doc file" is a bit too
