ippusbxd is the external program, sane-escl communicates with it over
network. So even if it works wrong, for sane-escl it is a kind of
invalid response from scanner. It should raise an error, not the crash.
Scanner also can send invalid response.

Running IPP-over-USB daemon may prevent sane-pixma backend from access
to the USB device.
But in general I think that if some device provides both proprietary and
"driverless" way of scanning/printing, driverless should be preferred.
So although for some particular user disabling IPP-over-USB may work as
a "hotfix", from community perspective this is better to investigate
IPP-over-USB issues rather that to disable it when it doesn't work.
