[regression] [[mediawiki:sidebar]] no longer supports entirely numeric headers ("* 3829")
don't have to be logged in to see the error. stack (below) varies depending on the skin in use. (broken with both monobook and vector)
probably broke sometime between 2014-08-10 (last revision before it was noticed broken @ wikimaniateam) and 2014-10-03.
lego says the bug is in Skin::addToSidebarPlain
