A page like the "Cannot find section" error  contains an articlefeedback page which seems inappropiate to me. This should be removed by checking that the page in question exists and that the page is currently being "view"ed (including action=purge and possibly other actions that show the articles content).
but not on an error page (ie. oldid= of inexistant revision or editsection-notfound)
Fixed in r87271.
