Hello it seems i discover a new bug in my 3.30 linux version:

when i do -N "%p/%[lang]/%n%[node].html" option.. i obtain
something like home/fr/home1.html and that's correct 

when i do a: -N "%[lang]/%p/%n%[node].html" option.. i
obtain  something like fr_/home/home1.html and that's not
correct. (lang=fr or lang=de... we have no lang=fr_)

Best regards
