Leandro, do you have the /var/spool/cups directory and does it have the correct permissions?
till@till:~$ ls -ld /var/spool/cups drwx--x--- 3 root lp 4096 2010-05-10 17:13 /var/spool/cups till@till:~$
You can fix this by reinstalling CUPS:
sudo apt-get install --reinstall cups
Do you have enough disk space?
