This problem affects version 1.6alpha on the live English 'pedia. The problem is that pages with titles like "Student's t-distribution" cause problems when displaying diffs, in particular the "title=" field in the URL and the links in the page tabs (in Monobook) are wrong. To reproduce this, do the following: 1. go to http://en.wikipedia.org/w/index.php?title=Student%27s_t-distribution&action=history (no problem there) 2. click on any two versions and then on the "compare..." button 3. the page that comes up has the wrong URL title= field and a different, but also wrong, page title, for example: http://en.wikipedia.org/w/index.php?title=Student&diff=21545885&oldid=20540703 Note how the title= field in that last URL indicates that the diff is about the article "Student", not "Student's t-distribution". The links to "article", "discussion", "edit this page", etc. as well as "rollback" all pertain to "Student", not to "Student's t-distribution".
Looks like some bogus JavaScript. Taking...
Incorrect quoting of escaped attribute value; cut-off but appears non-exploitable. Fix in revision 1.86 of includes/PageHistory.php.
