Patch is up and should resolve the problem. In the longer run we need better testing of this code path, but it's hard as you need a bunch of cross-wiki stuff setup in the test environment. Perhaps we can at least get it going in the browser test suite which already has multiple languages for testing analysis chains.

@dcausse

One lingering problem found here that is papered over by appropriately checking InterwikiLookup::fetch results, svwiki has renamed wikisource interwiki prefix from 's' to 'src'. We get the prefix from $wgSiteMatrixSites which is the same for all wikis. The end result is basically svwiki doesn't get (never got) sister search results for wikisource. Not the end of the world but would be nice to be able to source the data correctly. Unfortunately the only place i can find this variation, so far, is in InterwikiLookup itself. And the way it's data is layed out it's not possible to efficiently extract this from its data.

We could adjust mediawiki-config to change $wgSiteMatrixSites, but I don't understand it well enough to say it is 100% wrong to have the 's' prefix there.

@EBernhardson thanks for all your fixes.
I've never heard of this src prefix for svwikisource. I can have a look again at InterwikiLookup but the problem is that it uses completely different data than SiteMatrix and as you said is optimized for different purposes...
