A bit more. Installed the oneiric package (though I don't think it's a version problem) and started looking at what gets passed to /usr/bin/smb4k_mount

Original
sudo /usr/bin/smb4k_mount -s -t cifs -o uid=1000,gid=1000,port=445,rw,file_mode=0755,dir_mode=0755,noperm,nosetuids,noserverino,nomapchars,user=mimo,pass=XXXXX -- //192.168.03/Share /home/mimo/smb4k/DINGBAT/Share ; echo $?
Unable to find suitable address.

Changing this to:
sudo /usr/bin/smb4k_mount -s -t cifs -o uid=1000,gid=1000,rw,file_mode=0755,dir_mode=0755,noperm,nosetuids,noserverino,nomapchars,domain=GN,user=mimo,pass=XXXXXX -- //192.168.03/Share /home/mimo/smb4k/DINGBAT/Share ; echo $?
0

and it works.

For the record, if you get a similar error / problem it could be the port
