List mimetypes that default to a given .desktop file

I can list the mimetypes potentially handled by a .desktop file doing something like this: $ grep 'MimeType' /usr/share/applications/eog.desktop | tr ';' '\n' MimeType=image/bmp image/gif image/jpeg image/jpg image/pjpeg image/png image/tiff ... And I can show what the default application is for a given mimetype with gvfs-mime: $ gvfs-mime --query image/tiff Default application for 'image/tiff': eog.desktop Registered applications: eog.desktop gimp.desktop ... Recommended applications: eog.desktop gimp.desktop ... or with gio: $ gio mime image/tiff Default application for “image/tiff”: eog.desktop Registered applications: eog.desktop gimp.desktop ... Recommended applications: eog.desktop gimp.desktop ... But how do I list the mimetypes that eog.desktop actually handles?
