302 : Client error: Can’t edit post from requested journal

Right this post on every attempt to delete it or to edit shouts:

Something went wrong - 302 : Client error: Can’t edit post from requested journal

When I edit the entry by standart WordPress editor and press the button “Save” it complains but still save the changes. The useless discussion can be found there on WP support forum. It have been told that this is not a WP error. The list of HTTP status codes can be found at Wikipedia there. My client is FFox 1.5.0.1, WP 2.0.2. IE6 gives the same error.

Update: This is the usual situation using LiveJournal Crossposter WordPress plugin. The error appears when you delete your Livejournal entry but original post at WordPress remains. And then you edit the original WordPress post and save it. To avoid this error one should temporary disable the plugin I mention above.
