System Information
Windows 10 and NVIDIA Quadro 2000M

Blender Version
Broken: 2.76b f337fea and 2.77rc1 b594b25
Worked: never?

When applying a color ramp using small steps it appears that the width of each equidistant step is unequal on the rendered output.

Just open the attached blender file and render it with cycles. Then look at the material nodes and notice the equal spacing of the stops in the color ramp.

This isn't really a bug, but a limitation of look-up table caused by it's resolution. Will evaluate how safe it is to increase resolution here, but that'd happen outside of the bug tracker work.
