(Information how often this happens welcome for judging how urgent it is to fix)
What would be the am appropriate fix? Are special pages no longer allowed to use OutputPage::addWikiMsg and wrapWikiMsg?
(In reply to Niklas Laxström from comment #2) > What would be the am appropriate fix? Are special pages no longer allowed to > use OutputPage::addWikiMsg and wrapWikiMsg? OutputPage::addWikiMsg is fine. However OutputPage::wrapWikiMsg (along with OutputPage::addWikiText, OutputPage::addWikiTextTitle) never worked correctly when used from a special page that was being transcluded on a real page.
It's a huge chunk of the exception log now.

See https://www.mediawiki.org/wiki/Manual:Special_pages#OutputPage-.3EaddWikiText.28.29 "If your special page is intended to be included in other pages, you should probably not use addWikiText() (or any other function that calls the parser. Message). Due to a bug in MediaWiki (Bug 16129), an included special page will mess up any inclusion before it on the same including page, showing strings like UNIQ10842e596cbb71da."
Okay. It should be easy to not use those functions at all or at least not when transcluding the special page.

I'm seeing a similar error with 1.24wmf4 and Semantic Forms 2.7. This is the message I get when trying to use a Special:RunQuery embeded in a page. MediaWiki internal error.

Please file a separate bug for each extension. For now it is easier to fix this in each extension separately.

I suppose we could temporarily replace $wgParser with a new Parser object in SpecialPageFactory::capturePath. Not sure if its worth it. The OutputPage methods are really the only methods left where this is an issue.
