Comment 5 for bug 1464432

account-polld is the process triggereing this bug, but it's not actually the one which should be blamed. The bug is indeed in u-s-s-o-a, which in the RTM version doesn't properly check whether the trusted session could be created.

This bug should be already fixed in vivid: when account-polld will make its request, the trusted session won't be created (because account-polld has no UI), u-s-s-o-a will see that the request failed and will immediately return an error to the client. No UI will be displayed to the user.
