[O] [Bug] org-attach-set-directory

[Florian Lindner]

Hello,

doing C-a s <newdir> on an entry with an existing attachement produces

make-directory: Die Datei existiert bereits: /home/florian/test/data/<newdir>

(translation: File already exists)

Actually, I implemented this functionality with the help of Nicolas Goaziou, 
but it seems an org mode or emacs upgrade broke it.

I will try to debug that further, but right now, my time is very limited, only 
undershot by my elisp knowledge.

Maybe someone can more quickly fix that... ;-)

Best,
Florian
