System Information
Operating system and graphics card
win8, nvidia 880m 8GB

Blender Version
Broken: f1917a2
Worked: not known

Short description of error
trying to bake mixed shader with transparency generates artifacts if form of horizontal lines.
non-100% transparency mixing or not transparent materials never generate these artifacts.
I use these techique for texturing, as seen in the file.
artifacts are same without and with cage objects, they can change slightly with different tile size, or different ray length settings, but never disappear.

Exact steps for others to reproduce the error
example file:
testbakebug_texts.blend

bugtxts.jpg

bugtxtsexample.jpg
open the file, DON'T change selection, hit bake.

for illustration attaching screenshots from this file and another production file.

Forgot to note an obvious observation here: the artifacts start/end with start/ends of completely transparent areas...
