Can confirm bug is still there at link in description: http://ln.wikipedia.org/wiki/Et%C9%94%C9%9Bl%C9%9B

Tried testing on https://de.m.wikipedia.org/wiki/Wikipedia:Hauptseite with Opera version 26.0.1656.60, Windows 8.1, couldn't get error message.

Tried reproducing the bug, went to https://test2.wikipedia.org to test it out.

Tried to reproduce, couldn't do so on https://translatewiki.net/w/i.php?title=Special:Translate&group=mediawiki&language=zh-hans&filter=%21translated&action=translate&setlang=zh-hans, on Google Chrome Version 39.0.2171.95 m, Windows 8.1. Probably because this bug is pretty old and already has been fixed.

Sorry, but I can't reproduce the problem, in fact I can't find the site, being on Android 4.4.2, app version 2.0-r-2014-12-01
What I did (or tried to do) in extreme detail just so we are sure:

1. Open up the drawer from the left
2. Clicked on the "<Gear icon> More" button at the bottom of the drawer
3. Clicked on "Wikipedia language" under general
4. Searched for Bengali and clicked on it
5. Went back and searched for "নতুন নিবন্ধ তৈরী করুন" (I even copied and pasted it from this site)
6. Got the message "No results found" :-(
