Yep, but you did not reference image1 later in your code :-P And used
my way instead (recreating each time...)

Might be, depends on how it is solved internally. Anyway, even with
this overhead, the reactivity of the systray icon using TrayIcon
instead of StatusIcon is much better.

Two in the example, yes.

Maybe it's just me. I am obsessive about global variables. Usually I
only have $LOG_OF (file handle) and $DEBUG (easier to share with
modules).

I'm considering looking into the gtk sources -- I did look into the xs
files of Gtk2, but it seems all to be happening in gtk internals
(gtk_status_icon_set_from_stock). Maybe I shouldn't, though. I am
sitting at an airport on a way to a job interview  -- and I still
haven't prepared my presentation :-)
