Wire lines do not always correctly display when rendered. The attached file displays this better.

In the attached file there is a single mesh with two materials. The world has a black sky. One material is Halo of black color. The other material is a green Wire which emits light. There are no lamps. The resulting affect is glowing green outline of the edges of the mesh. The mesh is not transparent.

The bug is that the edges do not always display. In the blender file, the mesh is symetrical and the camera is centered. However only the lines on the top and right display when the scene is rendered.

Changing camera clipping does not affect the output.

Attached are the expected results, the actual results and the file which displays the bug.

I was able to reproduce this bug on
Windows 7 64 bit running Blender 2.65 r53189 (attached blend file was generated with this version)
Linux (Fedora 17) 64 bit Blender 2.64~ (compiled)
Linux (Fedora 16) 32 bit Blender 2.63~ (compiled)
