Launch Draw or Impress. Activate the Color Bar and undock it. You find it in View > Toolbars. Resize the Color Bar so that it has enough area to show all colors of the palette. Now the scroll bar should be removed, but it is still shown. That was OK in 4.1.0.0.alpha0+ (Build ID: 049ce78144650d92eb6bd73292868f73d37c901)
Confirmed with Version: 4.2.0.0.beta2 Build ID: 1a27be92e320f97c20d581a69ef1c8b99ea9885d Ubuntu 13.10. Set to New and change plateform to All - Sophie
