Ouch, I've put a typo in to the manual (now fixed).  verticalScrollbar
shall be verticalScrollBar (capital B).  If you change that and
widget_class to widget, does it help?

The problem is that these restrictions are not documented by GTK (for
example the fact that pixmap based scrollbars does not allow changes
for colors), so we just find them as they happen.

One extreme "solution" is to make Emacs behave as other GTK applications,
that is provide no customizations at all, except through themes.  That makes
documentation a whole lot simpler :-).

Until then, I'll add an example for this case to the manual next week
(going away for a week just now).
