Comment 5 for bug 36228

Thanks for this bugreport.

I can reproduce the problem here. It seems like xscreensaver/gnome-screensaver
makes all windows disappear from the wnck_screen_get_windows(), it returns a
empty list. So it dosn't detect that the screensaver is runing. Interesstingly
that behaviour didn't show when the screen is saved with
"gnome-screensaver-command --activate". That's why I didn't detected it in my
initial tests.

Cheers,
 Michael
