The size of a gtk window is determined by performing a size request on it, which recursively requests what size the window's child widgets want. Generally, widgets that get size requested ask their immediate children what size they want, add whatever size the widgets themselves want, and return that value. GtkScrolledWindows just return a very small value, despite whatever ridiculous expanses of screen real estate their children want.

It's all in the source, gtk/gtkscrolledwindow.c and gtk/gtkviewport.c :)
