Exception log from fluorine
To reproduce, visit http://commons.wikimedia.org/wiki/User:Pere_prlpz/gallery/14
One of the frames in the call stack is:
Scribunto_LuaSandboxCallback->formatNum('[[:int:lang]]U...', 41)
..which made me suspect Scribunto. But I haven't investigated.
Stack trace attached.
Version: unspecified
Severity: normal
Attached:
My initial reaction would be somebody doing mw.getLanguage( <random parsed wikitext here> ); - not enough error checking to handle the invalid language situation, Language::factory throws a MWException which nobody catches. But haven't looked into it to confirm that.
Change 116984 had a related patch set uploaded by Anomie:
mw.language: Fix exceptions and add tests
This should be deployed to WMF wikis with 1.23wmf18, see https://www.mediawiki.org/wiki/MediaWiki_1.23/Roadmap for the schedule.
