hi, as you can see from the BR this has been forwarded upstream. i have also found an ubuntu BR with very a very similar signature:
https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/101943 which unfortunately also did not have a solution. the compiz/compiz-fusion developers don't have much for ideas about what the problem could be either. also, i can reproduce this on my system in both kde and gnome environments. the system is not "locked up" when this happens, but the graphical interface is. that is, if you start ssh (beforehand, obviously) and log in remotely, you can still recover the system by killing the screensaver and compiz processes. therefore, i'm using the "nuclear option" to workaround this problem now, so that compiz can still be a viable candidate for lenny; i'm adding a conflicts from compiz-core -> xscreensaver-data-extra (non -extra screensavers shoudl still work). sean
