commit 3693cac9254023afaad7a681b525851f23eb2a15
Author: Tristan Van Berkom <tristan van berkom gmail com>
Date:   Sun Mar 28 13:31:06 2010 -0400

    	* plugins/gtk+/glade-gtk.c, plugins/gtk+/gtk+.xml.in:
    	  - Sync attributes when they are set to be used directly and not by the model (fixes loaded state
    	    of explicitly set cell renderer properties).
    	  - Fix last patch to reset cellrenderer attributes from a GladeProperty::value-changed signal
    	    instead of the property mutator implementation (as the "columns" property is construct-only
    	    and the widget is rebuilt - property reference lists are unavailable at ->set_property time).
