Description T. H. Kelly (Pink&) 2013-05-21 15:27:10 UTC 
If, for whatever reason, you try to access a page on en.wp with the prefix "User:Special:", you get the message "MediaWiki internal error. Exception caught inside exception handler." It doesn't matter whether it's a valid special page name ([[User:Special:Contributions]]; [[User:Special:NewPages]]) or not ([[User:Special:foo]]; [[User:Special:bar]]). It doesn't happen for any other combination of namespace prefixes I've tried: [[User:Wikipedia:foo]]; [[Category:Special:foo]]; [[User talk:Special:foo]]. It also doesn't happen on any other Wikimedia site I've tried: [[d:User:Special:foo]]; [[s:User:Special:foo]]; [[simple:User:Special:foo]].

Clearly not that big of a deal, but might be indicative of some larger issue.

Note that this does not appear to happen for logged-out users; I've tried this on Incognito on my Chromebook and on Mozilla on my PC (which I almost never use and thus am not logged in on), and it displays the standard empty userpage for these links.
Comment 2 T. H. Kelly (Pink&) 2013-05-22 04:42:24 UTC 
Hmm... [[testwiki:User:Special:foo]] and [[mw:User:Special:foo]], but not [[test2wiki:User:Special:foo]]. Something in one of the extensions, then, perhaps? Note that the testwiki error message conveniently gives details, unlike the en.wp one.

It seems quite likely that this caused bug 51399. Re-opening this bug for now as I suspect we'll see a revert in short order.
