Unexpected background colour

[Kip Warner <kip thevertigo com>]

Hey list,

I have a scrolledwindow / viewport in a gray GtkAssistant that is
painting a white background on Gtk 3.4.2-6 (Debian Wheezy). However,
the same application is not painting white on Gtk 3.6.4-0ubuntu8
(Ubuntu Raring). I prefer the latter behaviour and would like to stop
the whiteness so the region blends with the rest of the user's theme.
