I don't know exactly what happened so it doesn't work anymore (and it  
worked before) but script finalization is always a bit fragile. All values  
in all modules dictionaries (holding globals) are set to None (presumably  
to help garbage collection by breaking cycles). When your delete function  
is called, globals like shutil or files are already gone. A way to avoid  
this problem is to hold a reference to all required globals, so your  
delete function would become:

      @staticmethod
      def delete(files=files,rmtree=shutil.rmtree):
  	'''Called to delete all temp files'''
  	if files.tempdir:
  	    rmtree(files.tempdir)

But I'm not sure if this is enough because rmtree relies on the os module  
to do its work.
