[Nautilus-list] File associations not based on file extension

[=?iso-8859-15?q?=22Stormacq=2C_S=E9bastien=22?= <S Stormacq aubay-si lu>]

Hello,

I am using StarOffice 6.0's new file format (based on XML).  The files produced by StarOffice Writer 
are zipped files, with a SXW extension.

Nautilus recognizes these files as zipped files, not taking into account the .sxw extension and the 
settings I gave to gnome to associate .sxw and the StarOffice program.

How should I tell Nautilus to bypass the file recognition mechanism based on file structure (or 
internal ID I guess) and switch to a simple extension recognition ?

Thanks for your help
