This may well be the case in this instance, but I do believe
that similar message are sometimes issued without overt user error.
In the Porphtrogenitus Lexicon, for example, I am invariably told :

yet there is no mention of "page.1" in my source, nor
do I explicitly meddle with TeX's page numbering.
