Description: Handle problems encountered with docutils 0.6.
 The problem here is that the child.data element does not always exist any
 more.  Apparently, the child element is sometimes a string instead.  So, we
 work around it by only executing the code in question if child.data can be
 referenced. Thanks to Thomas Hille for research and the initial patch.
