Nautilus grief

[Rik]

When gnome fires up nautilus dies.

This is the error I get when I try to run nautilus from a command line.
What does it mean?

[leopard] ~> nautilus
0x0 : Freed()
xmlMallocBreakpoint reached on block 0

On another note why am I unable to search the archives on freebsd.org.
It always claims the archives are unavailable.  It is a true pain to
sift through all the subject lines by hand.
