Gwibber does not start in KDE

Binary package hint: gwibber

Gwibber won't start in either KDE 4.4.2 or 4.4.3. I get the following when run in a terminal:

** (gwibber:3565): WARNING **: Trying to register gtype 'WnckWindowState' as enum when in fact it is of type 'GFlags'

** (gwibber:3565): WARNING **: Trying to register gtype 'WnckWindowActions' as enum when in fact it is of type 'GFlags'

** (gwibber:3565): WARNING **: Trying to register gtype 'WnckWindowMoveResizeMask' as enum when in fact it is of type 'GFlags'
