+1 for this.

This is still happening on my Huawei MediaPad X1, just noticed it the other day. Don't do a lot of Wikipediaing on that device.

For the record, rebooting only corrected the problem after the app had been uninstalled and the Chrome app data cleared (not just the cache, everything). The problem persisted through 2 or 3 reboots before this.

2.0-r-2015-01-15 on both devices. The app defaulted to English.

Not temporary and not fixed. Also happening on my Huawei Mediapad X1, latest Chrome on 4.4.2.

Apologetics for the delay. As an example, if I type "wikipedia" into Google on Chrome, the second result is Main_Page, and that throws the error, attached. Clicking Open on wikipedia.org underneath the result opens it in the app; although I'm not sure that's the correct behaviour. There are also links to the Wikipedia and Wiki pages in the search results, and they work fine.
