In my small anime related wiki I had a page named ".hack//Sign" (without the quotes). Such a title was accepted and links to it worked nicely in 1.5.0 version of mediawiki combined together with PHP 4.x. After I have updated the wiki software to 1.7.1 and PHP to 5.1.4 the links to this page do not work anymore. When I click on them I always get to (an empty) page titled ".hack/Sign". The same thing happen if I try to enter a page named ".hack///Sign" or ".hack////Sign" and so on. Setting a redirect to the old page solves the problem, however.
Double-slashes aren't valid in page titles now. Run maintenance/cleanupTitles.php to rename broken pages to something valid.
