Description of Problem:
Getting a traceback when attempting to run this routine on my desktop machine. 
The traceback is:

Traceback (most recent call last):
  File "/usr/share/hwbrowser/DeviceList.py", line 163, in ?
    setup_ui ()
  File "/usr/share/hwbrowser/DeviceList.py", line 156, in setup_ui
    DeviceDisk.initialize (xml, hardware)
  File "/usr/share/hwbrowser/DeviceDisk.py", line 485, in initialize
    populate (tree_view, disks, graph)
  File "/usr/share/hwbrowser/DeviceDisk.py", line 379, in populate
    raise RuntimeError, ("can't handle more than "
RuntimeError: can't handle more than one extended partition per disk

Which is all the more interesting when you consider this:
