Systray: What is the naming logic for the Systray configuration?

[Christian Esken]

Hello,

I would like to rename the entry from KMix to "Volume Control" in the
sytray configuration dialog (Systray->ContextMenu->Configure->Entries->Element 
column).

How can I set the name? It's not from the desktop file - I already tried that. 
I also browsed the Techbase without success, e.g.  
http://techbase.kde.org/Development/Tutorials/PortToKStatusNotifierItem.

PS: Background is http://bugs.kde.org/show_bug.cgi?id=270632, and I tend to 
agree.
