Email template override doesn't work + language detection

Following your two tutorials I copied the email files from the component wireframe theme folder to my_template/html/com_easyblog/emails/html folder.
But that doesn't work (currently I check it in the back-end Mail Activities page). If I directly hack the files in the wireframe folder I do see the modifications.

There is another issue - picking the right language ini file. Currently it only takes the text from the en-GB file. Since I'm checking it from the administrator site (which is set to English), I'm not sure what triggers the correct email language. I believe it should be depended on the content language... but it doesn't.
