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
(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:
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".
Incorrect quoting of escaped attribute value; cut-off but appears non-exploitable.
Fix in revision 1.86 of includes/PageHistory.php.
