Seen on my local setup. Seems to be related to LanguageConverter somehow; of the wikis set up by the Vagrant langwiki role, it only affects zhwiki and zhwikivoyagewiki.

Beta srwiki (the only Growth wiki which uses LanguageConverter) is not affected. Either the issue is specific to vagrant or specific to the Chinese wikis' (significantly different) language conversion configuration.

This (or something very similar) exploded when 1.36.0-wmf.2 moved to all wikis a few minutes ago.

But production srwiki is, apparently. Do their language settings differ somehow?

Probably the immediate trigger was rEGREb2bc51779bf1: HomepageHooks: Convert to HookHandler which converted a bunch of hooks to the new system (meaning the dependencies of all hooks are fetched when any hook is invoked). Some subsequent patches build on it so it's not trivial to revert but we can revert together with followups if we are in a rush.

So, various hooks (including some very common ones like MessageCache::get or UserGetDefaultOptions) cause HomepageHooks to be instantiated, with GrowthExperimentsConfigurationLoader as a service dependency. The configuration loader tries to create a Title (from which the configuration will be loaded); that involves a namespace check, which in turn involves LanguageConverter::convertNamespace, which is customizable via system messages, so MessageCache::get is invoked again. The triggering hook varies, but otherwise it seems to be the process for all logged errors.

There is a code quality improvement patch waiting for review, but the actual bug was fixed, so let's close this.
