Look at the results for:
SELECT page_id, page_title, page_is_redirect from ruwiki_p.page where page_title LIKE '1648%';
The result contains 4 pages, two articles and two redirects. The redirect named '1648' is ok, and the other one is wrong, because its name is unreachable via Wikipedia web-interface. Because all the names with the first symbol after last digit are substituted with names with underscore (space) instead.
Is it possible to delete this wrong page, moreover this page is a double-redirect.
This is a non-breaking space (0xa0). Currently these are allowed in titles, but some browsers (including Firefox) like to silently change them into regular spaces when you submit them in form data.

Thanks, it really works in IE. This is a good reason to keep it installed on my PC =).
The redirect now thrown.
Еxplanation was quite simple :-)
