Comment:

 I've taken a look at this issue and so far have not been able to establish
 any dependency on shared-mime-info hidden or not.

 As you've said, as currently configured, gdk-pixbuf auto-configures
 whether or not to use gio sniffing based on a test program that calls two
 gio functions, g_content_type_guess() and g_content_type_from_mime_type()
 using an inline png test image.  If both routines return the same result
 then the gdk-pixbuf gio code is enabled.  If not, gdk-pixbuf uses another
 approach using internal data for guessing the mime type.

 I thought perhaps this meant that glib (home of gio) depended on share-
 mime-info as you imply but this appears not to be the case either.

 In my final test, I did a clean build of glib2 and gdk-pixbuf2 by first
 deactivating all installed ports, then doing a forced rebuild of glib2 and
 gdk-pixbuf2 in that sequence.  I have confirmed that shared-mime-info is
 not active at any time during this process and yet the gdk-pixbuf2
 configuration test passed and gio sniffing was enabled in gdk-pixbuf2.

 So, unless you have further evidence to the contrary, I don't think there
 is anything to be done here.
