This isn't about redirects or bad layouts, the server is simply not responding when sending a mobile device user-agent header.
Opening https://wikitech.wikimedia.org/w/index.php?title=Special:Contributions&limit=100&target=Krinkle in Chrome with an Android user-agent string simulated result in a 404 response (not a redirect first, the url itself is directly rejected)

No such page
Cannot look at history for a page that doesn't exist. It may have been deleted or you may have followed a bad link.
I'm not sure where this is coming from, I've never seen this type of error.
https://wikitech.wikimedia.org/wiki/Special:Contributions is also broken. But https://wikitech.wikimedia.org/wiki/Special:Contributions/Krinkle seems to work fine.
