Error in translation statistiks

Screenshot

I had three undone messages in mw 1.18 and also three in MediaWiki total shown in the tranlation statistics for ksh. Each of them was marked fuzzy. I corrected two, then I had still three undone ones in the MediaWiki group, and two in 1.18 as the attached screen shot shows.

Later, I found that a newly added message, MediaWiki:Fileduplicatesearch-noresults had appeared in MediaWiki core, but MediaWiki core had not been shown in the translation statistics before I translated the message now. With one untranslated message, it should have been listed!

If I'm reading you correctly, this is a symptom of the known (to us at least) statistics caching bug.

OK, I wasn't sure.
