This > involves e.g. creating a new MIME type. Thanks for this hint. Here's what I've found: I started with a clean Lenny install + gnome-desktop-environment pulled in. I then registered a custom mime type on my user as described in http://library.gnome.org/admin/system-admin-guide/stable/mimetypes-modifying.html.en (See attached file, which I put in ~/.local/share/mime/packages/ and then ran "update-mime-database ~/.local/share/mime/" to generate the mime.cache.) I verified with gnomevfs-info ~/Desktop/foo.abc that my test file was actually detected as the new mime type text/x-abc. I upgraded to squeeze... After the complete upgrade gnomevfs-info now told me my file was of type application/octet-stream rather then my custom type. Double-clicking my test video file opened the movie player without problems, no error message about mime mismatches or anything. To get my custom mime type back I had to manually invoke "update-mime-database ~/.local/share/mime/" and then foo.abc was again detected as text/x-abc by gnomevfs-info. It seems the mime cache is now simply ignored if it's in the old format. > > > I wonder if this problem might have only been a concern for > > testing->testing upgrades back in 2009.... > > It was a problem with lenny→squeeze upgrades back in 2009, but it might > simply have been fixed upstream. Semi-fixed it seems. I wonder where this leaves us now... -- Andreas Henriksson
