Well...it definetly is that theme. My best guess would be that it is being caused by not systray2 as it isn't loaded, but by the even older systray2-lsbox. It looks like the theme.rc also contains an install for vtray. I wonder if it would be wise to switch to that instead of that stupid lsbox systray.

Another idea would be to switch to a theme like 18 or 21. I know both of them work just fine. They also load systray2-2.0.1.dll in a box instead of systray2-lsbox. Good luck guys.
