Beta > CB >Copy a resouce to the same collection. A message shown, "This resource is corrupted; please remove it from your collection"

CB > Click Copy link of any resource.
In Add a REsouce window, select the same collection iteslf and proceed.
The copy of the resouce has to be displayed in the CB. Now I can see the copied resouce name. But the resource is shown corrupted.
"This resource is corrupted; please remove it from your collection." message is shown.

I got this issue in beta alone. In dev site it works well.
