Thanks for your report. Is this still happening? If so, please run "apport-collect 520464".

I'm hitting this bug as well. The only thing special about my system is that I use KVM to virtualize some machines beneath it. This results in some additional less common network interfaces, a couple of bridges, and removes IPv4 addresses from the eth interfaces.

This bug is reported on a 6 year old version of arping. Please try to reproduce with a never version, or run with -vvvvv to increase verbosity.
