+
+     <para>
+      This change extends fixes made in the last two minor releases for
+      related failure scenarios.  The previous fixes were narrowly tailored
+      for the original problem reports, but we have now recognized that
+      <emphasis>any</> error thrown by an encoding conversion function could
+      potentially lead to infinite recursion while trying to report the
+      error.  The solution therefore is to disable translation and encoding
+      conversion and report the plain-ASCII form of any error message,
+      if we find we have gotten into a recursive error reporting situation.
