 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.
