Thanks Jan for following up on these even after I failed to provide a screenshot.

 

This is not the same thing as what the OP said.  He changed the theme values, the above only change the Emacs values.
Most theme scroll bars can not be resized.  So Emacs always use the theme values for the scroll bars.  So if the theme values changes, Emacs should use them.

But the OP didn't say which Gtk+ version, which theme and which Emacs version he was using.

 GNU Emacs 24.0.90.1 (x86_64-pc-linux-gnu, GTK+ Version 2.20.1) of 2011-11-03 on lychee, modified by Debian

Gtk theme is Murrine Brave Dark.

I modified these lines in gtkrc

    GtkRange       ::slider-width        = 10 # Scrollbar width.
    GtkRange       ::stepper-size        = 0 # Stepper height.

This is what the scrollbars look like in most other apps:

(though Gedit and Gvim both display them wrong)

This is what they look like in Emacs by default:

Note that the slider is the right width, it's just the trough that is wrong.

If I use (add-to-list 'default-frame-alist '(scroll-bar-width . 10)) then they look correct:

I've seen this in other themes that I haven't modified myself.
