Good day,
I've managed to resolve the problem as follow:

1) Stop the cups daemon:
   # /etc/init.d/cupsys stop
2) Remove the CUPS drive cache file:
   # rm /var/cache/cups/ppds.dat
3) Rerun the cups-driverd query from the command line to rebuild the
   #/usr/lib/cups/daemon/cups-driverd list 1 0 "requested-attributes=all
4) Restart cups:
   # /etc/init.d/cupsys start

5) Adding the printer from the web interface works now perfectly.

It beats me why the database got toasted...
