This is expected. You should not make assumptions about the state of the global Parser instance in a special page. In some circumstances (especially transclusions) it might be in a parse, other times it won't be.
If you're rendering an i18n message, its better to use ->parse() of the Message class then to pass it through the parser directly.
Alternatively use \MediaWiki\MediaWikiServices::getInstance()->getParser()->getFreshParser() and then initialize it yourself by calling ->parse() on the Parser, so you always know what the state is for sure.

Hi everyone,
my skin uses the global parser in order to render some parts of the navigation bar via templates (Parser::recursivePreprocess). This works fine on all normal pages (and even some special ones like Special:Version), but not on special pages like Special:AllPages.
Some debugging revealed that on Special:AllPages the global parser object (\MediaWiki\MediaWikiServices::getInstance()->getParser()) is not properly initialized. Member variables like mOptions and mTitle are null which results in tons of NPEs.
Any idea why that is? Is that a bug or am I mis-using the parser?
