ifupdown segfaults

Would just like to point out that

UpgradeStatus: No upgrade log present (probably fresh install)

is wrong.

One line above is
InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5)
which is right -- thats when this machine was installed

And in my view this is clearly an upgrade problem because with 15.10 booted from live USB there is no such issue

[Just in case others look here]
It looks that commenting out all of /etc/network/interfaces seems to remove
this problem

[Does it cause new ones?? No idea... Right now net is up (wired) Wireless
is down but thats been so since wily upgrade, ie a couple of weeks]
