Nautilus string freeze break request

[Alexander Larsson <alexl redhat com>]

I'd like to fix:

Bug 565610 – Replacing folder with file from within that folder destroys
both: http://bugzilla.gnome.org/show_bug.cgi?id=565610

However, the fix includes showing an error dialog, so it introduces a
few strings:

_("You cannot move a file over itself.")
_("You cannot copy a file over itself.")
_("The source file is overwritten by the destination.")

Patch and bug is described in bugzilla.

Is this ok?
