I just stumbled over this:
Create a SWFolder Foo, edit the text and save. Edit again and change the
title to Bar and save again. Now go to the history and revert to the
first version named Foo. After that you get a page not found error on
Foo. If you now enter manually the former URL for Bar you get a page
with the original contents of Foo! :()
Hopefully this ain't FUBAR. ;)
