Random Trackbacks automatically happening within website

I don't know if this is related to http://drupal.org/node/13865 -- this certainly counts as "over-aggressive" but what I'm experiencing is Trackbacks within my own site, pinging other posts. I am not entering any trackback URLs, but this is happening anyway. Trackback seems to be grabbing internal site URLs on its own -- how, I don't know.

The problems seem to happen just with revising "book" pages. (I have a series of site information pages linked together in a book. These pages get updated now and then.)

For example, if I make an edit to my "faq" page or "housekeeping" page, trackback goes and pings a trackback to another post seemingly at random. (One time it was another user's blog. The most recent time it was a blog entry of my own -- I got the first few lines of my own faq page posted as a trackback to one of my own unrelated blog posts.)

Another problem is the persistence of the trackback. I can go ahead and delete the trackback comment where it appears, but I cannot delete the trackback URL from the original page's post. I can see the data there displayed at the bottom of my book page info when I edit the page, but I cannot get at that info to delete it. So there seems to be no way to correct this erroneous behavior. Frustratingly, the next time I go and revise that page, the trackbacked pages will be pinged yet again.

I posted this as "critical" because it's something that can make a total mess of a site, not to mention rather embarrassing. (Why is she trackbacking her own posts at random?) I don't have the busiest site, but already it's a problem, confusing other users and leaving me very frustrated.

I hope this is helpful and can be debugged and fixed soon. Thanks!
