Bug#457357: nautilus crash in files properties

[Federico Muciaccia]

Package: nautilus
Version: 2.18.3-3

Trying to view files properties (expecially images and sounds) from the
right-click menù nautilus crashes, all open windows disappear and, after
one second, a new window positioned in ~ (home) appares.
Executing nautilus from terminal not returns any arror during the crash.
Executing nautilus as root (sudo nautilus) returns this error:

Gtk-ERROR **: file /tmp/buildd/gtk+2.0-2.12.1/gtk/gtkliststore.c: line
1677 (gtk_list_store_compare_func): assertion failed: (VALID_ITER
(&iter_b, list_store))
aborting...
Abortito

(the last word means aborted in italial)
Files were not of large size (normal images such as splash screem or
normal audio track).

I am using Debian GNU/Linux testing (lenny), Kernel 2.6.22-3-686, GNOME
