[X2Go-User] pyhoca in Ubuntu 14.04 LTS with Unity

I tried to launch the pyhoca-gui on my Ubuntu box but it did not go to the panel. So I searched for a solution and found the hints on

http://wiki.x2go.org/doku.php/doc:usage:pyhoca-gui.

But unfortunately the hint to use

gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"

does not work in Unity on Trusty as there is no entry com.canonical.Unity.Panel in the gsettings. Using dconf-editor I tried to find whether there is something similar or whether it had been moved into another tree but there is no node for Panel in no tree.
