Easy question of the day: One of our headnodes is barking when I use --fields with nova.

nova list --all --fields=host,instance_name,status ERROR (TypeError): '<' not supported between instances of 'str' and 'NoneType'

This works fine with the other headnodes, and all 3 are supposed to be the same (hardware, software). Would that indicate a bad installation or something else? Where should I be looking for answers?

Looks like a simple bug in the version of python-novaclient on this host, can you try using --debug to get some more information and comparing the version between a working and non-working host?
