Try navigating to a page before writing to the Document object. The
code below worked for me...

ie = WIN32OLE.new("InternetExplorer.Application")
ie.Visible = 1
ie.Navigate('about:blank')
sleep(1) while ie.ReadyState != 4
ie.Document.open
ie.Document.write html
ie.Document.close
sleep 5
quit 

Hope that helps.
