Florian I try and try for solving the problem first i think it was the server,
because in I change the language (locale) and I can download,
then I thing it was the server. But I never had saw the erros in the /logs/ folder,
and it saids that for some reason label.inc had send something to the buffer (before headers),
but i saw and the wasn't any space. So I take the easy way copy the array for the label.inc
into another label.inc that hasn't the problem for me it was "en".
So i put the translation into it and upload, then the errors said that now
the problem was messages.inc I make the same and now it works.

The answer was in
http://roundcubeforum.net/forum/index.php?topic=1645.msg6657The problem is that the locales inc were enconded in another charset
in linux with the program enca I can see that en is a 7bit ASCII characters text
and de_DE is Universal transformation format 8 bits; UTF-8
So the answer is that the locale must be in 7bit ASCII characters text.
You can do it in linux :
iconv -c -f utf8 -t ascii old_file.inc > new_file.inc
So old was utf-8 the new is ascii.
