# 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.
