Actually the ordering of addons paths has changed between 1.7.0 and 1.7.1 as an unwanted side effect of some refactor.
This can impact code that expects at import time that openerp standard addons have already been imported. The sooner it'll be fixed, the less code in the wild will depend on the inverted behaviour
(The arbitrary import from http.py module is a very bad thing, but it's not ours to fix).
Note also that this an area where there can be a difference between split setup (server + addons + web) and the nightly releases
