fileCreatedDate() method asumes that the ole invoke for fileCreatedDate will
never fail.
In one of our tests we hit upon an OLE errror for image. The to_s() was calling fileCreatedDate which intern gave an
WIN32OLERuntimeError



--------------Test Script--------------------
require 'watir'

a=IE.attach(:title, "xxx").frame("xxxx")
puts a.image(:index, "1").to_s
