This can't be right.  N_ only makes sense around a string literal (e.g. in 
a constant initializer); it marks a string for extraction for translation, 
but does not cause it to be translated at runtime.  You need _() to cause 
the translation at runtime (and then make sure that every string constant 
that can end up as a value of reason is surrounded by N_() - or just 
surround the string constants directly by _() if there isn't a reason that 
won't work).
