Worked: 2.75a c27589e

Short description of error
Now we have a new operator, "Clean Channels", which removes the channels in which there is no animation.
Old operator, "Clean Keyframes", always left one key in the channel, in such cases. But now it works the same, as "Clean Channels", and remove channel.

Why do you need that 1 key channel?

If I switch to another action, and I do not have that 1 key per channel, it can damage my animation.

It seems that the bug only reproduce after a run "Clean Channels" operator. It runs bpy.ops.graph.clean(channels=True), and save property "channels" as True for next calling bpy.ops.graph.clean()

The operator "Clean Keyframes", in this case, have to called with bpy.ops.graph.clean(channels=False)

Sounds like both clean channels and clean keys are actually the same operator, and probably blender's operator memory is saving the last used option. Humnf
