Attempting to run `scanimage -L` produced: Process 12178 launched: '/usr/local/bin/scanimage' (x86_64) dbus[12178]: arguments to dbus_connection_send() were incorrect, assertion "connection != NULL" failed in file dbus-connection.c line 3311.

Do you ask to make AVAHI OFF by default?
> Do you ask to make AVAHI OFF by default? No, I think having the AVAHI option on by default is reasonable. Your comment and some more searching suggests that the segfault is a consequence of not having dbus & avahi active. This seems like an upstream bug, hpaio should just remain inactive if dbus or avahi is not available. IMO the avahi dependency ought to be mentioned in pkg-message though, because the failure mode is a non-obvious segfault and because avahi isn't actually needed (for the scanner backend).
(In reply to Ed Maste from comment #4) Can you please help me with pkg-message? My english is poor. :-(
> Can you please help me with pkg-message? I have not yet actually tried again with avahi running, but I presume the crash will be gone. For pkg-message, how about: Ensure that avahi is running, otherwise some backends may crash.
/usr/local/lib/sane/libsane-hpaio.so.1 was installed by package hplip-3.20.6 Updated port in summary, I incorrectly submitted against libsane. It should be an upstream bug against hplip and a note in hplip's pkg-message, I think.
And, I can confirm no more abort() after # service dbus forcestart Starting dbus. # service avahi-daemon forcestart Starting avahi-daemon.

Rename the SNMP option to NETWORK because it's not just SNMP now. - Don't install some programs related to uninstalling and upgrading of HPLIP and the installation of firmware plugins because they circumvent the package system. - Install icons in share/icons so desktops can choose an appropriate resolution.
