pygvfs_mime_application_new has:

    return Py_BuildValue("sssOONO", mimeapp->id, mimeapp->name,
                         mimeapp->command,
                         mimeapp->can_open_multiple_files? Py_True : Py_False,
                         mimeapp->expects_uris? Py_True : Py_False,
                         uri_schemes,
                         mimeapp->requires_terminal? Py_True : Py_False);

However, mimeapp->expects_uris (_expects_uris with DISABLE_DEPRECATED) is of type GnomeVFSMimeApplicationArgumentType:

typedef enum {
	GNOME_VFS_MIME_APPLICATION_ARGUMENT_TYPE_URIS,
	GNOME_VFS_MIME_APPLICATION_ARGUMENT_TYPE_PATHS,
	GNOME_VFS_MIME_APPLICATION_ARGUMENT_TYPE_URIS_FOR_NON_FILES
} GnomeVFSMimeApplicationArgumentType;
