I've uploaded at [1] a patched version of libXt, which includes some extra
debugging output, including the name of encoding which is causing this
warning, based on a patch at [2].  (This patch isn't really suitable for
upstreaming as it needs to be wired up to libXt's rather confusing error
reporting and localization scheme)

This should at least allow us to discover the name of the encoding which is
causing the warning.
