When I modify Murrine Brave Dark as described above, I do get smaller scroll bars in Emacs.  The scroll bars in gnome-terminal and Emacs look exactly the same.  But this also depends on font size.  Emacs pads the scroll bar to a multiple of the font size.  That is because if you do a C-x 3 there is nothing to take up the slack if the scroll bar is different from the character width.

I don't think there is a bug here. This is a known limitation in Emacs, and so far there has been no work into remove it.
