Let's forget the pnm backend. I have to admit I wasn't clear enough. The
offending command is scanimage -L. So I just disabled the pnm entry from
the dll.conf. That means that I have only the net backend listed in
there and so it should return "No available devices" or something.
Instead of that I am getting...

Assuming I haven't configured properly the saned service in inetd.conf,
scanimage shouldn't core dump, should it?
