[Sugar-devel] [PATCH sugar-toolkit-gtk3] Make sure we have a widget before attaching an invoker, SL #3460

[Simon Schampijer]

The _ToolbarPalette does get passed the invoker on
initialisation. But we do create the PaletteWindowWidget
later. We do attach the invoker to the widget when calling
_setup_widget that is why it was still working without that
patch.

This patch prevents the traceback that we had because of not
having a widget at this point.
