System Information
Windows 7 Pro 64bit w/SP1, 8GB RAM; NVIDIA GeForce GTS 360M 1GB VRAM

Blender Version
Broken: ver. 2.69.11 hash 4acff9d; ver. 2.69.0 r60995
Worked: don't know

Short description of error
Since I don't use the GPU at all to render on my laptop because my CUDA graphic card is no longer supported by Cycles, I just noticed the following error messages being displayed in the console when I use any of the Light Path node's outputs as a factor to mix a Glass shader with a Transparent shader; discovered when I added the Shadow + Diffuse + Glossy Rays as an input for the Fac value of the Mix Shader node (see attached screenshots).

This happens as soon as I click on Material in the Viewport Shading drop down list. Despite the above error messages, the render process seems apparently to work without any problem. So, I'm not even sure it's a bug but I'd like to know the reason behind it, and if it can affect the CPU render process in some way or not. Thank you.

Exact steps for others to reproduce the error
Please, find attached a sample file and while you are in the 3D View select the Viewport Shading to be Material to generate the error.
