Comment(by mikafoobar):

 Ok, what does "enforcing permalink history would fix this" mean for me? :)

 I just stumbled once again upon this issue (updating timestamp to send
 updates via RSS but old URL is non-existent anymore then). :(

 Is this something which is already available or is this something which
 has to be implemented yet? Sorry, couldn't find anything about it, I just
 see "2.9" in the milestone property so I guess this is something not
 available yet, right?

 Thanks.
