The FileChooser ToolKit (fctk) had its own machinery to handle default sizes which was completely busted and trying to marshal random numbers through the widget hierarchy that maybe made sense in 2012 but don't do now. Get rid of it, just keep the dialog's GSetting - which funnily enough used to be written by the dialog but written by the widget. But that's fctk for you.
