sawfish-ui problems

[Mark Diekhans <markd kermodei com>]

The sawfish-ui in svn isn't working well,  as can be 
seen in these images:

Here the +/- is missing from the tree:
  ftp://osprey.kermodei.com/pub/sawfish/sawfish-config1.png

the Appearance node doesn't open by clicking on it, generting:
    *** Required argument missing: #<closure make-widget>, 4

Once Bindings has been clicked on, the Appearance can be opened,
although it generates:
    *** Invalid function: ()

Text is missing in many places:

  ftp://osprey.kermodei.com/pub/sawfish/sawfish-config2.png

any ideas?

thanks
mark
