After a browser restart I ended up to a page of a qaiku on an channel (#aamua, todays qaiku). The page UI was mostly in Finnish, but the links in the banner, which take you to different qaikus on that channel were in English ("< Previous" and "Next >") and the text where Add a comment box should be was in English too "Login or register to leave a comment". The buttons below that were in Finnish.
@jiivonen, Sounds like a small context bug on the used platform. I'll ticket this and see if we can fix it ourselves (are we the ones to blame :) or is it some minor annoyance with #midgard version that we are running now (and if so, it might be fixed on newer versions).
