[PATCH] Only consider selection when deciding whether deletion is possible

[Christian Neumair <chris gnome-de org>]

Nautilus used to query whether the displayed location is readable when
deciding whether files are readable. It should rather consider the
selected files themselves.

Proposed patch attached, should fix bug 316301:
