I have a rule which I am trying to convert into a template with Smart Clone.

The hierarchy is:
global project template
 -> Qt - All Platforms
  -> Qt 4.5 arthur tests trial

Doing a Smart Clone of `Qt 4.5 arthur tests trial', with the smart clone fields left as default, fails with the message "Invalid path: path is empty". The following message appears in the server log:
