What I had to do:
apt-get install --reinstall snuggle
and even
apt-get purge snuggle
left the .snuggle folder as user:root, so I deleted them manually after removal
rm -fr /home/user/.snuggle
rm -fr /home/user/.config/snuggle
apt-get install snuggle

The location of that csv file is hmm, I would say 90/10. It is really private information so I would like to keep it on hidden folder (maybe change again to /home/user/.snuggle owned by root? so it is separated from config files?) and file owned by root. Easier acces would of course be on MyDocs (iStyle)...
