There are couple problems here.

First, not every widget Settings have property "gtk-toolbar-icon-size".

Second, I get following messages when I am trying to reparent my toolbar 
to another window (prehaps, it is related to bug I've submitted on 
toolbar items are inactive after reparenting).

Gtk-CRITICAL **: file gtkwidget.c: line 2221 (gtk_widget_realize):

There is back trace from debug if someone would to see it at all:
