PPA "Copy packages" issues

[Bruce Cowan]

I'm having trouble using the PPA "copy packages" facility. I am trying
to use it to copy packages from one release to another (Hardy->Intrepid
and vice-versa). When I try to do this, I get an error - "same version
already has published binaries in the destination archive". The only way
I can copy packages is to copy the binaries.

Is this a bug, or am I doing something wrong?
