System Information
Operating system and graphics card

Blender Version
Broken: 2.72b 9e963ae
Worked: 2.70 and earlier.

Short description of error
Graphical fragments baked into textures while baking

Exact steps for others to reproduce the error

Steps for Blender 2.71 and higher:
Open file and click Bake.

Steps for Blender 2.70 and lower:
Open file and click on Bake.

2.70 will bake as intended. 2.71 will make graphical fragments into the bake. (purple frame in the example).

Note: Blender 2.72b is tested and still makes fragments.

In my tests on this file it appeared that these "fragments" are a second image texture bleeding through. The material has two overlapping uv-mapped image textures, and these spots happen only in that overlap zone, and they appear to be the color of the underlying image (the wooden frame). They don't correspond directly to any faces as they are much smaller than the faces they occur on.

No, it's not up to Dalai, it is up to @mont29 instead. Caused by 9b0ab89. I'm not sure why would epsilon need to be negative, his leads to wrong barycentric coordinates check making them less watertght.
