Before 1.1, I had no problem with those black edges showing up on my meshes. With 1.1, it was said to remove those edges (which I didnt really see) but I now see them, and quite often. I'm sure it is just my meshes which I receive from clients and are built in AutoCAD. The topology is absolutely horrible and takes forever to round edges, ect.

Anyway, is anyone else having this problem, or just me? I am also using Blender and the exporter hasn't really been updated since before 1.0 came out, so maybe the settings need to be updated as far as normals, ect.

For me, I had black edges on glossy materials in curved areas not enough subdivided, when using Smooth.

These black edges disappeared with 1.1 ! :)

They remain when using Smooth on flat surfaces, as they do in Blender as well, but as there is no need to use Smooth on flat surfaces, everything works fine !

Could you post some pictures? It could be that the face normals are pointing in the opposite direction to the vertex normals, but it's hard to say without any images or a scene.
