Django admin 'save_as' with inlines

Question

Should 'save_as' work with inlines. I'm rather baffled by the traceback but it doesn't seem to show much involvement of my own code.

The problem seems to be the id's of inlines being set to '' when saving an add form. This is handled quite happily by when you do a normal 'add':
