[Nautilus-list] non latin-1 icon text of desktop icons and others are broken

[KUSANO Takayuki <AE5T-KSN asahi-net or jp>]

Nautlius HEAD can't display icon text of desktop icons correctly on
non-latin-1 locale. They are displayed as '???? (invalid Unicode)'.

These are caused by validated_strdup() function in
libnautilus-private/nautilus-desktop-file-loader.c.

I've replaced validated_strduop() with g_strdup() and nautilus becomes to
work fine (LANG=ja_JP.eucJP).

I think encoding conversion (utf-8 -> locale encoding) is not needed
on GNOME 2 environment.
