Thank you for testing, though the issue is not fixed. The problem was that a 
tar.gz could be detected as a tex font
not the opposite. Mea culpa for the fast and too short bug report.

I did not ship the tar.gz (way too big) though i paste the relevant part of the 
file in my report 
When the site works (dynamic ip :( you can reach my copy on 
http://prahal.darktech.org/debianbugs/GTK2-AluminumAlloy-Volcanic.tar.gz


>From my first report:


the start of the tar.gz
0: 037 213 010 000 021 117 005 100  000 003 354 134 011 074 124 373
AluminumAlloy-Volcanic/[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL 
PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@^@ in ascii

to compare i put an extract from a random tex font:
/usr/share/texmf/fonts/tfm/public/misc/manfnt.tfm
0: 001 023 000 022 000 000 000 177  000 065 000 020 000 005 000 011
[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@^

then the rationale i was able to make from the "file" too "database" (file 
myfile.tar.gz was detected as tar.gz when
 nautilus via shared mime info data - obviously using the "magic" detection not 
the extension - detected it as a 
tex font).
I also focused on the tex font pattern.


/usr/share/misc/file/magic line 9730
# There is no way to detect TeX Font Metric (*.tfm) files without
# breaking them apart and reading the data.  The following patterns
# match most *.tfm files generated by METAFONT or afm2tfm.
2   string  \000\021TeX font metric data
>33 string  >\0 (%s)
2   string  \000\022TeX font metric data
>33 string  >\0 (%s)


/usr/share/mime/packages/freedesktop.org.xml line 3138







tar.gz 
0: 037 213 010 000 021 
   ^^^
tex font:
0: 001 023 000 022 
   ^^^


so i guessed that shared-mime-info count from -1 :(

the issue could have remained unnoticed by most as if the offset is wrong for 
all pattern shared mime info will
fail back to extension matching.

The issue still exists with 0.16-3.


I really hope i am wrong as changing the offset now that the freeze happened 
would mean any of the thousands of patterns
may have unknown bugs. Better ship the broken tested version for sarge ...

Alban

I haven't had a chance to digest the entire of your email.

However most of the magic patterns do work. For example rename an
OpenOffice spreadsheet removing the .sxc spreadsheet and it is still
detected as a spreadsheet using the following magic


  

I can't look at this at moment as I am in the middle of my finals. Will
try to look at it in a couple of weeks.

 Could you please attach the first bytes (as output by head --bytes) of
 the file?
