The first entry of this menu ( http://goodies.xfce.org/_detail/projects/panel-plugins/xfce4-places-plugin-screen3.png?id=projects%3Apanel-plugins%3Axfce4-places-plugin ) doesn't work as expected: It mounts the drive but doesn't open a Thunar window with its contents. In fact it's the same whether you choose "Mount and Open" or just "Mount". Using xfce4-places-plugin 1.3.0-3 in Arch Linux: https://aur.archlinux.org/packages.php?ID=34568 It might be related to some of the patches used by the packager, but at least the first one (01_use-preferred-filemanager.patch) isn't the cause of the problem (I tried building the package without it).
