https://de.wikipedia.org/w/index.php?title=Wikipedia:Spielwiese&action=edit&uselang=sr-cyrl is also affected. It seams to happen when values from Wikidata are included in the page.
Fomafix renamed this task from Fatal exception when using uselang=sr-cyrl or uselang=sr-latn on Wikidata to uselang=sr-cyrl and uselang=sr-latn causes fatal exception of type "MWException".Oct 19 2018, 8:52 AM

Given that uselang processing is involved, perhaps https://gerrit.wikimedia.org/r/460039 is the proximate cause.  Can we get a stack trace for that exception?
cscott added a comment.Oct 19 2018, 11:38 AM
Also -- sr-cyrl, zh-hans-tw, etc are not actually the mediawiki-internal names for these languages. https://gerrit.wikimedia.org/r/460039 would have added support for using the standard names, but I'm a little bit surprised that anything is generating links to these "non-mediawiki" (but BCP 47 standard) codes.  I mean, it's good -- we *should* be trying to move to using the proper BCP 47 codes -- but it's worth trying to track down where these links are coming from, since they wouldn't have worked prior to 460039.

Ok, merged T207447: uselang=zh-hant-hk causes fatal exception of type "BadMethodCallException" into this one, because the stack trace is pretty much identical:

In both cases, LanguageConverter->translate() is being invoked with a BCP 47 code, not a mediawiki-internal code.  SrConverter and LanguageConverter (used for zhwiki) handle this in slightly different ways, but the root cause is the same.  This appears to be a Wikibase bug, it is not converting BCP 47 codes to mediawiki-internal codes appropriately.



Unfortunately, no referrer field is present in either log entry.



In the past seven days only 32 hits for BadMethodCallException (most of which are not this bug).  41 hits for the exception in LanguageSr, though, most of which are this bug.  So not super-high frequency.  I'll figure out root cause and write a patch.
cscott added a comment.Oct 19 2018, 2:23 PM
Arrrrgh.  WikiBase/lib/includes/LanguageWithConversion.php contains code cut-and-pasted from mediawiki-core.  Anyone want to guess the odds that it wasn't updated when the code from core was updated?
Fomafix added a comment.Oct 19 2018, 2:33 PM
I generated the URLs containing uselang=sr-cyrl myself. They are not generated by a link.
cscott added a comment.Oct 19 2018, 2:46 PM
Ah, ok, thanks!  That means I don't have to worry about this being an "unbreak now" sort of bug.



https://gerrit.wikimedia.org/r/468589 is a stopgap at fixing the issue, but there's a deeper confusion between BCP 47 and mediawiki internal codes which is causing the BCP 47 codes to make it into Wikibase's LanguageFallbackChain.  Still working on that...

OK, two patches to fix the issue: belt and suspenders.  Both of them are potential candidates for cherry-picking to 1.32, but let's get them merged on 1.33 first.
