I was following this link on solidifying edges. When I went to convert the mesh to a curve, nothing happened. Here's what I starting with a new file:

Ctrl + F > Wireframe
Tab back to object mode
Alt + C > Curve from Mesh/Text
Nothing happens. I noticed that it works if I add a Grid or Circle and try to convert those. What am I doing wrong?
I have Blender 2.71 (Release Candidate). I also tried converted the cube directly without converting it to a wireframe, but that didn't work either.
