Here is the list of quantum commands that consistently fail:

quantum agent-list
quantum floatingip-list
quantum net-external-list
quantum net-list
quantum port-list
quantum router-list
quantum subnet-list

* Note that there are also successful quantum commands ("quantum ext-list" and "quantum quota-list").

Command for example
===================
# quantum net-list
Request Failed: internal server error while processing your request.


# quantum net-list --debug
Request Failed: internal server error while processing your request.
