sane crashes

[Vlad D. Markov]

I am having some problems using sane for scanning.

My version of FreeBSD:
FreeBSD happy 12.1-RELEASE-p2 FreeBSD 12.1-RELEASE-p2 GENERIC  amd64

My version of sane:
happy$ scanimage -V
scanimage (sane-backends) 1.0.29; backend version 1.0.29

I have tried multiple approaches to get things working:

The scanner is an HP so I set the URI and tried:

happy$ xsane "hpaio:/net/OfficeJet_Pro_6970?ip=192.168.1.37"
Assertion failed: (p), function avahi_threaded_poll_lock, file thread-watch.c, line 171.
Abort trap (core dumped)

Next try:

happy$ scanimage -L
Assertion failed: (p), function avahi_threaded_poll_lock, file thread-watch.c, line 171.
Abort trap

Recompile minus Avahi:
happy$ scanimage -L
device `hpaio:/net/OfficeJet_Pro_6970?ip=192.168.1.37' is a Hewlett-Packard OfficeJet_Pro_6970 all-in-one

Maybe this will help the next person.
