Steps to reproduce: null-edit the first section of the page at the URL. Observe the difference. Then revert yourself so the next person can try. The problem is obvious: almost all sections start on a new line, so nobody bothered to put any logic in to check if the next section has a line break before it.
It seems that the current MediaWiki version does not count the second H2 as a valid section (which is a correct behaviour), therefore, this bug does not occur. (http://en.wikipedia.org/w/index.php?title=User:Simetrical/9266&action=edit§ion=2 leads to an error stating there is no section 2). Marking as WORKSFORME (or, maybe RESOLVED would be better?).
