Bug#502941: gnome-screensaver: Infinite recursion for cyclical symlinks

Package: gnome-screensaver
Version: 2.22.2-2
Severity: important

A cyclical symlink will cause an infinite recursion through the directory 
structure of /home/username. This will eat memory and 
quickly cause out of memory conditions until the process is terminated.
