modrewrite weirdness with pingback

[matija]

i'm gonna describe my problem and solution i make:
i wrote a 'page' about something, doesn't matter, let's name it 'lookme'. this page was accesible via modrw url mydomain.com/lookme. after some time, i decided to migrate it to 'post'.
i rename page name and page slug, added -old at the end. new url/name is now mydomain.com/lookme-old. i rename it while i was copying data to new one, then i delete old 'page' so only the new 'post' exists.
since then, no pingback come to this post. i check server settings, xmlrpc.php, upgrade wp to 2.2.2, nothings happen. i go deeper in code, and i found, that function url_to_postid returns nothing, while in db, i still found 'lookme-old'.

solution that works for me: i deleted row from wp_options (rewrite_rules), and generate new one via admin > options > permalinks. now works fine.

problem, i think, or solution: should you delete 'old' rules if some page is deleted and recreate another one?

I was not able to reproduce:

1. Created page with slug "original-page"
2. Published page
3. Edited page, renamed slug to "new-page"
4. Verified that rewrite_rules were updated

If you did any part of that manually (by manipulating the database) you shouldn't expect it to work. Could you explain the series of steps one must take to trigger the bug in a little more detail? Can you reproduce the bug now?

hm, i don't think that i was modifying db. but now i tested just like u said before. create page, edit page, rename page & slug, delete page ... check db, no record was there. strange. anyway, works now :)
thanks, greetings
