Potential problem with Skin Modifier and Cycles Smoke (2.70 buildbot on Mac)

Just a quick heads up - I’ve had some strange issues rending a scene with a skin modifier and cycles smoke. I am not a tthe computer right now, so I can’t post screenshots, but there were several odd polygonal artifacts extending out of the object with the skin modifier when rendered with cycles smoke. The artifacts are not present in the preview window, and the problem is resolved if the skin modifier is applied.
