On new install of 12.10 (AMD64 architecture) this bug appeared.
Notice that 12.10 is using XFCE 4.10 as standard, so no need for PPA.
Additional information:
* When trying operations requested on comment #2, observed same behavior as comment #12
* Regarding power button, it does nothing when pressed, as reported on #6 and #8.
* Also installed Ubuntu then XFCE components, like in comments #14 and #15.
* Package indicator-power *is* installed. Removing indicator-power might be an option for some but it's a kludgy workaround as it probably deprives users running gnome or unity from seeing battery status :-/.
* After doing like in comment #12 (kill -9 was needed, --quit or plain kill was not enough), power manager can be tuned via XFCE parameter tool and works (e.g. suspends when closing lid, if configured that way).
* Also, the system experiences bug #1048805. It might be a hint as both bug show a message "Did not receive a reply." The local fix for power manager does not fix that bug, still.
To summarize : the scenario of a conflict between Gnome and XFCE components seem plausible.
