 If hald is not running, the following traceback happens:

 {{{
 Traceback (most recent call last):
   File "/home/sugar/sugar-
 jhbuild/install/share/sugar/extensions/deviceicon/volume.py", line 86, in
 _setup_volumes
     _mount(volume, tray)
   File "/home/sugar/sugar-
 jhbuild/install/share/sugar/extensions/deviceicon/volume.py", line 103, in
 _mount
     volume.mount(gtk.MountOperation(tray.get_toplevel()), _mount_cb)
 AttributeError: 'module' object has no attribute 'MountOperation'
 }}}

 There are several other candidates for disk hotplug detection: Fedora 11
 seems to be going to use [http://fedoraproject.org/wiki/Features/DeviceKit
 DeviceKit-disks] (which might turn out not to be much better for embedded
 systems, though). A udev helper script could notify Sugar as well (would
 need to be installed, of course).
 At the very least, the exception should be catched, though.
