I suspect that warning is for developers, not users.
It would be nice if those kind of errors were only produced if debug
package was installed - or if started with a switch asking for it.

The message may not even be part of xpdf but from a library xpdf uses
(perhaps uses incorrectly or in a deprecated way that will break in
future - hence a warning)
