I was wrong.

The message is caused by a bug in gobject-introspection which fails to
make the g_bytes_get_data method available to Python.

The bug occurs in Fedora 18, and is gone in Fedora 20.

Workaround is a ​patch to use unref_to_array instead of get_data, but
this won't work on later versions of gobject-introspection.

With the switch to microformat backend, and this patch, the updater
works now.  It has offered TurtleBlocks and Pippy updates.

The change in gobject-introspection which fixes it is in
gir/glib-2.0.c in the g_bytes_* sections.

Being tracked at
http://dev.laptop.org/ticket/12878

p.s. the ASLO backend also has a bug were it will stall the update
under certain conditions.  The underlying cause is that
__downloader_complete_cb may return without emitting the
check-complete signal.
