Ok, I see. All my LaTeX PDFs have #nameddest=section.x values instead
of #page=X values, so that's the reason they don't work. It would be
good if we could mention that it won't work because there are no page
references in the outline in the error message.

Thanks, will try with those two files.

Yes, but only if the older names pdfdraw and mudraw already had the
"show <file> outline" feature.

Will try with the large two you've linked later.
