Bug#666757: python-gtk2: warns about mismatched gtype registration at startup

[Drake Wilson]

Package: python-gtk2
Version: 2.24.0-3
Severity: minor

When starting any Python GTK+ program, the following warnings appear
from somewhere in the GNOME stack (demonstrated with a direct import
from the Python REPL):

> Python 2.7.3rc2 (default, Mar 21 2012, 06:59:11) 
> [GCC 4.6.3] on linux2
> Type "help", "copyright", "credits" or "license" for more information.
> >>> import gtk
>
> ** (process:18976): WARNING **: Trying to register gtype 'GMountMountFlags' as flags when in fact it is of type 'GEnum'
>
> ** (process:18976): WARNING **: Trying to register gtype 'GDriveStartFlags' as flags when in fact it is of type 'GEnum'
>
> ** (process:18976): WARNING **: Trying to register gtype 'GSocketMsgFlags' as flags when in fact it is of type 'GEnum'

This doesn't happen when importing gobject or glib by itself, so I
assume this is related to python-gtk2.  I haven't detected this
affecting any application behavior yet, possibly because I haven't run
any Python GTK+ applications that make use of the types involved.
Expected behavior: no such warnings appear.
