xfce4-power-manager doesn't show icon on panel

[Bela Markus]

xfce4-pwer-manager (1.2.0) doesn't display icon on panel (4.10). Strange 
enough it was working fine back testing on 4.10pre but now it doesn't 
appear. Daemon is running, configured 'Always show' but nothing.

Debug output running on a notebook with power connected at startup and 
later disconnected and reconnected is available at

Any idea welcome.
