System Information
Windows 7 and Radeon HD 5450

Blender Version
Broken: 2.69, 4789793

Short description of error
Incorrect preview of mixed anisotropic shaders with differing data.

Exact steps for others to reproduce the error
Add cube.
Add material.
Add mix shader.
Add two anisotropic shaders.
Set rotation on one of the Anisotropic shaders to .25

At this point, the material preview should be incorrect. For extra visibility of the issue, set the mix number to .999 and then tick it up to 1.

Could you try with a more recent build ? I don't see anything weird or incorrect in 2.70 9caf7029, also an image that demonstrates what is correct and what is not would be nice.

I updated blender (c6d8540). Same result.

Alright, here's an example blend file. Cube.001 has material.001 and looks correct
Cube has material. The preview looks incorrect.

Can confirm that now, seems that the issue is caused by the roughness.
