I am seeing the same error, I have exported a form from my live site which is running the latest public release, and imported it onto my test site which is running the 1.6rc5. When you enter the edit screen and click update form the error appears.
When I check the confirmation tab on form settings panel the radio button setting (text. page or redirect) hasn't been remembered. Also checking the properties tab for the start paging panel for the first page the radio button setting for the progress indicator also hasn't been remembered during the export/import.
As soon as I put those radio buttons back to how they were on the live site then the form saves correctly when you click update form, however for some reason it then forgets the radio button setting for the paging progress indicator and the next time you hit update form the save error returns.
