Description of problem:
When adding a custom mime-type for an ASCII file-type, the file is
*always* mis-identified as text/plain.

In my case, I'm trying to set up correct mime-handling for xmGrace
project files. These are ascii-text files. I can add a new mime-type
for this (i.e. application/x-xmgrace, I couldn't find a pre-defined
one on the web) and give it a file-extension '.agr'. After doing this,
all *.agr files are still identified as text/plain and opened with
gedit. (I also tried using text/x-xmgrace but didn't make any difference)

Also tried editing /usr/share/mime-info/gnome.mime, gnome-vfs.mime and
/usr/share/mime/mime/magic but nothing seems to help.


Version-Release number of selected component (if applicable):
2.6.0

How reproducible:
Always

Steps to Reproduce:
1. Save a text file with some custom file-extension
2. Add a custom mime-type for that file-extension
3. Attempt to assign a custom mime-handler for that file extension
    

Actual Results:  File is *always* identified as 'text/plain', whatever
the user does

Expected Results:  The file should now have been identified as the new
custom mime-type and handled appropriately
