[totem] opensubtitles: Use Gio introspection

[Bastien Nocera <hadess src gnome org>]

commit 9dcaa8e710db8be808e843f99dea3998b644291d
Author: Bastien Nocera <hadess hadess net>
Date:   Mon Sep 12 15:18:39 2011 +0100

    opensubtitles: Use Gio introspection
    
    And use Python's OS module to implement the reading
    as we won't be getting a working "read()" for Gio from
    Python any time soon (see bug #621915)
