System Information
Ubuntu 12.04.5 LTS -
Nvidia GeForce 6150SE/nForce 430

Blender Version
Broken: (Blender 2.76 RC1)
Worked: (optional)

Short description of error
Just a note: This works fine in BI (haven't tried it with BI nodes however). It is cycles where this issue seems to occur whether using nodes or not.

Exact steps for others to reproduce the error
(1) Start Blender 2.76 RC1, go into cycles, drag down a window and select the node editor. Make sure the node tree type is set to "shader" and "Use Nodes" is checked. Also, make sure "Viewport Shading" is set to "Material".
(2) On the diffuse shader node, hover the cursor over the color input (ie; white) and then use "I" to set an initial keyframe (frame 1#).
(3) Advance to frame 10# and set another keyframe on the color input of the diffuse shader node (again, white) and then use "I" to set another keyframe.
(4) Now, change the color of the diffuse shader node input to a different color at frame 11# (ie; blue) and repeat the same steps as in 2# and 3#.
(5) Now play the animation back in the viewport.

The expected behavior would be that from frame 1-10 the cube would remain white and then suddenly change to blue starting at frame 11. I've also attempted this with the emission node, tried tweaking various settings, etc and can't seem to get it to work - even though shader node colors/properties display just fine in the viewport, I can't seem to be able to animate them.
