Eject icon disappears from usb hardrives in Thunar

[jEsuSdA 8)]

Hi!

Since last package update (Debian Testing) I noticed the "eject" icon 
was disappears from Thunar when a USB Hard Drive is connected.

I was able to eject this disks (unmount + stop rotating) before this update.

I was some problems with consolekit and shutdown/mount/unmount/etc. but 
I solved them.

The only think I can do is eject the usb disks (usb stick works fine, 
but usb hard drives does not).

Can anyone help me, please.

Thanks!
