Normal scrollbars lack up/down buttons

[Teo]

On 14.04, I have disabled the annoying, and buggy overlay scrollbars that I've hated since they appeared, with the method described here:
http://ubuntuhandbook.org/index.php/2013/10/disable-overlay-scrollbars-ubuntu13-10/

So now I have "normal" scrollbars, which is good, except that THEY LACK THE UP/DOWN BUTTON that should be present at the top and bottom (either an up button at the top and a down button at the bottom, or both either at top or bottom).

Why the developers of Ubuntu keep destroying the usability of such basic, obvious things as scrollbars, is beyond me.

This is a preference that can be set by the GTK+ theme. It has nothing to do with Unity.

Thanks for correcting the package.

Importance should be changed to "medium":

https://wiki.ubuntu.com/Bugs/Bug%20importances
A bug that has a severe impact on a non-core application.
A bug which impacts accessibility of a non-core application.
A usability issue that does not limit the functionality of a core application.

It could even be "high" if for example Nautilus is considered a "core application"
Impacts accessibility of a core application

Unless you can tell us what's the easy workaround, in which case it could meet this criteria in the importance "low" definition:
Bugs that have easy work-arounds
