Hard code freeze break for Nautilus

[Cosimo Cecchi <cosimoc gnome org>]

Hi,

I've been fixing a few nasty crashers in Nautilus master this weekend,
and some of these apply to the gnome-2-32 branch too.
I created a gnome-2-32-fixes branch [1], which has four commits I'd like
to backport to 2.32.0; the most important commit are the top two, which
fix two frequent crashers, but I think it'd be nice to have the whole
branch merged to gnome-2-32.

Thanks,

Cosimo
