Package: libdjvulibre21
Version: 3.5.25-1
Severity: important
After upgrading libdjvulibre21 to 3.5.25-1, djview4 stopped showing
hyperlinks. It looks like ddjvu_document_get_pageanno() returns just an
empty list. I attached a small test program to illustrate this problem.
With libdjvulibre21 3.5.24-9:
$ ./extract-anno djvulibre-3.5.25/doc/old/lizard2005-antz.djvu 0 | wc -c
2895
With libdjvulibre21 3.5.25-1:
$ ./extract-anno djvulibre-3.5.25/doc/old/lizard2005-antz.djvu 0
