If you enter a "diff" URL that specifies revisions from two different pages, the MediaWiki software will generate a diff between them.
Steps to reproduce:
Visit a URL such as http://en.wikipedia.org/w/index.php?title=Wikipedia_talk:Bots&diff=36063763&oldid=879
MediaWiki generates a "diff" page between an ancient revision of the "Sport" article and a recent revision of the "Wikipedia talk:Bots" page.
What should happen:
MediaWiki should generate a very polite error message.
This is intended behavior.
Addition to comment #1:
