One additional note: GNOME Terminal uses a setup wherein when you start a new GNOME Terminal, and you already have other ones running, the new process just asks the old one to open a new window and exits. So, prior to testing for this bug's resolution in the development version of AllTray, be sure to not have any GNOME terminal windows open. A workaround will make it into the new AllTray later to try to change this behavior, though that fix depends on another issue in that release that needs a resolution.
A decent way to test it is to start an xterm and start "alltray gnome-terminal" from within xterm.
