What is the "path name"? Do you mean the "URL"?

This is exactly, how "path" should work:

     It turns a path into an object, in this case into a "PortalFolder"
     object.

     As the generated HTML can only contain strings, ZPT calls
     the "str" method on the object. This results in
     "<PortalFolderI instance at ...>".

What you need to do:

     Pass the path string itself as value of the hidden variable.
     Use "restrictedTraverse" in you Python Script to resolve it
     into an object.
     Call "setDescription" on this object.
