  Fix a missing unlock in case of error, and a missing free().
  
  Always free the allocated memory for a string field, because
  we are always using it (not only when xmldocs are enabled).
  Also if there is an error allocating memory for the string field
  remember to unlock the list of registered applications, before returning.
