    embed-prefs: Fix memory leak when setting languages
    
    This was a tough one. It's a GArray rather than a GPtrArray, which led
    me on a wild goose chase trying to set a clear function for the array...
    the clear function is not allowed to actually free memory, since GArray
    is not designed for holding pointers.
    
    This code should probably be refactored further.
