Thunar volman does nothing for audio CDs on insertion

[Maximilien Noal]

Hello,

I have gvfs installed and running :

thunar-volman too :

> ps aux | grep volman
> max      11159  0.0  0.3 320852 14000 ?        Sl   mai27   0:00 
> thunar-volman --device-added 
> /sys/devices/pci0000:00/0000:00:05.0/ata4/host3/target3:0:0/3:0:0:0/block/sr0
> max      22261  0.0  0.0  10676  1116 pts/0    S+   00:12   0:00 grep 
> volman

And yet putting :
/usr/bin/mousepad
OR
gvfs-mount cdda://sr0
OR
anything else (like sh -c "/usr/bin/mousepad")

does nothing in the "command:" textbox available from 
thunar-volman-settings -> multimedia -> Audio CDs.

And yet, all those commands do work in a terminal. Nothing appears 
either when I mount the cd in Thunar.

Does anyone has any clue on this ?

I'm using all the latest Xfce packages available on Archlinux. That is :
- Xfce 4.10
- Thunar 1.6.3
- Thunar-volman 0.8.0
- gvfs 1.16.2

My optical drive is /dev/sr0

Max
