System monitor showing impossible amounts of memory

Binary package hint: gnome-system-monitor

I've noticed gnome-system-monitor showing impossible amounts of memory. I've posted my (the.dark.lord) screenshot of this app regarding this problem on http://ubuntuforums.org/showthread.php?t=633661 .

"free -m" shows :-
