Yeah, cancel my previous theory (two instances of the screensaver running at once). I've just had access to the computer again - the bug is still there and there's no sign of any second instance. It is possible to stop the screensaver by killing gnome-screensaver while Kaffeine runs, so I'm marking this a gnome-screensaver issue too.
