Description Matthias Clasen 2008-06-18 08:07:31 UTC 
gdk-pixbuf uses a one byte longer magic for gif than shared-mime-info. 
Not sure it makes any difference, but here goes:

        static GdkPixbufModulePattern signature[] = {
                { "GIF8", NULL, 100 },
                { NULL, NULL, 0 }
Comment 1 Bastien Nocera 2008-06-19 02:10:03 UTC 
It's supposed to start with "GIF" followed by the type of GIF, so 87a, or 89a (IIRC). So GIF8 would match both, but wouldn't match a newer version of the format (unlikely as it is).

* freedesktop.org.xml.in: Better magic for GIF files,
from gdk-pixbuf, spotted by Matthias Clasen <mclasen@redhat.com>
