XFCE4 Thunar does not automount USB flash drive

Hi,

After a fresh install of Slackware64 -current I noticed that XFCE4 Thunar does not automount USB.

Running dbus-launch thunar, I have this messages:
Code:$ dbus-launch thunar
Error creating proxy: Error calling StartServiceByName for org.gtk.vfs.UDisks2VolumeMonitor: Process org.gtk.vfs.UDisks2VolumeMonitor exited with status 127 (g-dbus-error-quark, 25)

Does anyone know how to solve this?
