#153 clone ce creating two copies?

[Andy Deans]

I cloned a ce, and two copies resulted. This has happened multiple times, but I thought I was dreaming.
cloning this: .../projects/12/ce/show/24517
resulted in these:
/projects/12/ce/show/24731
/projects/12/ce/show/24732 (this is the one I was redirected to, and which I subsequently edited)
