That may not be so arm-wavy actually considering this has been a problem for a while and we haven't exactly been inundated with complaints, especially since on RH & (I think) Fedora distros SystemTray isn't supported anyway unless you install gnome-shell-extensions.

But hmm .. there's a thought - so long as available returns false anyway (via the existing code) do we even need to make this call ? Might need to be careful about when/whether the selectionListener is added.
Alexander can you look at that to see if we can just not bother with the exec if it isn't going to be needed anyway ?
