2 different scrollbars in the light themes

I didnt notice this until i was actually trying to scroll-down in a firefox window which had already reached the end of page, [ http://launchpadlibrarian.net/41378725/Screenshot-Mozilla%20Firefox.png ] notice the arrow is dimmed and there is a gap which makes it seem that there is still some page left , while notice the scrollbar of the other window.

Confirming bug from dup.

While the problem is related to "GtkRange::trough-under-steppers = 1" in the theme gtkrc, let me clarify that this is a GTK widget style property, and *not* a Murrine engine option [1].

XULRunner-based applications (such as Firefox, Thunderbird, etc.) seem to ignore some (or all?) GTK widget style properties. Another property that gets ignored is "GtkNotebook::tab-overlap". In my Dichotomy theme [2] I have set the "GtkNotebook::tap-overlap" property to -1 which should have the effect of spacing tabs 1 pixel apart. This works in all applications except those that are XULRunner-based [3].

I also forgot to mention: OpenOffice.org also does not seem to respect style properties; this is hardly surprising, since it's all-round GTK support is quite poor.

Same problem in Opera 10.51

Why not just get rid of the steppers? Many community themes have done so. Newer platforms such as Android and iPhone OS have also done so. Does anyone use steppers?

(To see how it would look, you can add GtkScrollbar::has-forward-stepper = 0 and GtkScrollbar::has-backward-stepper = 0 to the theme's gtkrc -- this works with all applications except OpenOffice.org.)

This problem also affects the "About Ubuntu" dialogue in the System menu.

fixed in maverick
