nautilus does not mount sshfs volume when set in /etc/fstab

Binary package hint: nautilus

#In My /etc/fstab there is :
(...)
sshfs#hamacker@192.168.1.3:/home/vol/caixa_entrada /media/caixa_entrada fuse rw,users,user,nosuid,auto,nodev,allow_other,umask=000 0 0
# Then create mount point and permitions
mkdir -p /media/caixa_entrada
chmod 777 /media/caixa_entrada/

# Add to /etc/modules (is default in Ubuntu Gutsy, but not default in Feisty)
fuse

# Add to /etc/fuse.conf
user_allow_other

# Add my user to group `fuse` (not default in Ubuntu Gutsy)
adduser hamacker fuse

# set my login `hamacker` to login in 192.168.1.3 without a password (ssh-keygen -t dsa) and OK.
Testing to mount /media/caixa_entrada without password via terminal is OK.

Go to nautilus, open address bar and type sshfs://hamacker@192.168.1.3:/home/vol/caixa_entrada is OK too.

Go to Nautilus, open left panel, choose `caixa_entrada` and right click and set 'Mount' does not run, a icon representing harddrive `caixa_entrada` appear in desktop area and disapear too fast and /media/caixa_entrada are not mounted.

No log in /var/log/messages and no any message on screen to describe whats happen.

The same method runs OK in nautilus when Ubuntu Feisty.

Any idea whats happen ?
It's a nautiilus error or the same method does not run anymore ?
