Thunar doesn't crash when I manually mount the usb and navigate to the
mount point (through Thunar).

When I manually mount usb:

root at debian:/media# mount /dev/sdb1 /media/usb0/
root at debian:/media# exit
exit
shicy at debian:/media$ thunar
^C
(Thunar didn't crash, so i closed it)


When mounted through Thunar:

root at debian:/media# umount /dev/sdb1
root at debian:/media# exit
exit
shicy at debian:/media$ thunar
thunar-volman: Unsupported USB device type.
thunar-volman: Unsupported USB device type.
