I'm glad you included the full output like that.  I don't know if I would have ever figured out what was going on without seeing the "Current Language is..." text. 
 
So here's what I've found so far: if you change the language by right clicking on the main chat box and selecting a language, everything works fine.  But if you use the /language command (which I forgot existed), it doesn't seem to actually change the language (even though it does update it in the select language box).   
 
I'll try to figure out what's going on with /language; hopefully it'll be something simple and I'll be able to get a fix out tonight or tomorrow.
