[Secure-testing-team] Bug#482385: xscreensaver disappears (segfaults/aborts?) when xrandr is used.

[Pierre Habouzit]

Package: xscreensaver
Version: 5.05-1
Severity: grave
Tags: security
Justification: user security hole

  When xrandr is used to resize the screen on my laptop (because I use
an external 16:9 lcd screen at work, and the lcd panel of the laptop
else and those don't have the same resolution) xscreensaver completely
disappears, I assume it dies at some point.

  Then if I close my LID so that the laptop is locked when I'm AFK, it
doesn't lock anymore because xscreensaver simply isn't there.

  If xscreensaver is unable to support xrandr, it should at _LEAST_
restart on its own.
