Yep, it's as odd as it sounds. When I start a GNOME session from a fresh boot (via GDM called by /etc/init.d/xdm, etc.) and never open Thunderbird (ver. 2.0.0.21), gnome-screensaver (ver. 2.24.1-r1) activates just fine. However, the second I open a Thunderbird instance (and even if I close it and make sure no thunderbird processes exist), gnome-screensaver never kicks in automatically- I have to manually start it via the menus/tray icon. I have confirmed and the screensaver configuration doesn't change; the same options as before are selected per System > Preferences > Screensaver. Firefox does not seem to cause this behaviour (I haven't tested any other mozilla apps).

I wish I could be of more help but to be honest, I'm at a bit of a loss as to where to even begin troubleshooting this.
did you try with an alternative screensaver ? (xscreensaver for example). CCing teams that might be interested.
please get back to us.
