Actually the root cause for the failure I did observe was different. This appears to be a genuine nova error where a server is deleted by another test while the list operation is in progress. It is also interesting that nova fails with a 404 here - this appears to really be a bug.
In support of my thesis I can provide examples where the same failure trace occurs with[1], [2] and without [3], [4] neutron Also, during a server list operation there is no interaction between nova and neutron.
