I had only a quick look at this and it seems the ports are chosen
randomly by the operating system. saned creates the socket and
transmitts the port no to the net backend. I have added a TODO entry
for documenting this issue. Maybe we can find a nicer solution for
SANE 2.

Depends on what you mean by "dies unexpectedly". segfaults etc.
shouldn't happen in the backends (-->bug). Could you write what you
did and send a debug log (saned -d and maybe SANE_DEBUG_MUSTEK_PP=255)?

Is this a problem of running it with -d or with the high debug level?
Do you run saned -s as root (probably necessary for PP scanners)?
Otherwise, a logfile would be nice.
