Lubuntu 14.04 [1] maps the power button as follows:
<!-- Launch logout when push on the shutdown button -->
<keybind key="XF86PowerOff">
<action name="Execute"> <command>lxsession-default quit</command>
</action>
</keybind>
This configuration may interfere with xfce4-power-manager. Also, the power manager is probably not able to call and display the Xfce logout dialog without an active Xfce session.
