[orca-list] initialization errors

[Christopher Moore <chris w1gm gmail com>]

Hello,
I'm getting the following errors when launching gnome3 / orca-3.01.
I've seen similar error messages in recent posting to the list.  

** (orca:3393): WARNING **: Trying to register gtype 'WnckWindowState' 
as enum w
hen in fact it is of type 'GFlags'

** (orca:3393): WARNING **: Trying to register gtype 'WnckWindowActions' 
as enum
 when in fact it is of type 'GFlags'

** (orca:3393): WARNING **: Trying to register gtype 
'WnckWindowMoveResizeMask'
as enum when in fact it is of type 'GFlags'

What causes these messages?  I'm concerned that gobject or some other 
package may be out of date.

TIA
Chris
