first of all, this xscreensaver behaviour is a feature, not a bug: the
new xscreensaver just doesn't show the * anymore, and it makes sense to
reset the timer on key presses. i still loose the keyboard though.

not every times, but it just happened again, and when xscreensaver was
not locked. i could see the mouse for a while after the screen woke up,
then lost everything, even alt+tab. i then moved to console and killed
xscreensaver. X segfaulted again then (i attach the Xorg.0.log, which is
very similar to the one i sent already).

Option "AllowDeactivateGrabs" "boolean"
This option enables the use of the Ctrl+Alt+Keypad-Divide key
sequence to deactivate any active keyboard and mouse grabs.
Default: off.
indeed, looks like it could help me getting the keys back. i will see if
that helps.
