Summary:
Render artifacts with mat node
Detailed description
I am using r33030 64bit with debuggin on ubuntu 10.10 64bit.
This is originally a 2.4x file, but it is the only file I have that seems to have render artifacts, so I thought you guys might be interested.
I tried turning on/off everything from ray tracing, to amb occ, adjusted mat settings, and nothing I tried got rid of the problem. In fact, it tended to get worse.
I have attached some screenshots of renders from 2.49b and r33030, along with the blend file itself.
Hope this helps, cya.

looking into this report, looks like it could be uninitialized memory.

Problem seems to be related to the texture node used by material node.

The texture was not packed in, but I see the error. It has todo with the node setup, but currently the material node editor seems to have more issues, can't even select nodes here to inspect material settings!
One suggestion though: if you use a material as "node root", you shouldn't use that material inside its own node tree.
