--- Comment #3 from Tobias Wich <tobias.w...@electrologic.org> --- I did some further testing and the document seems to be the problem. I created a new PDF without the form fields, so the PDF does not contain the AcroForm dictionary before singing. When I sign this document, the AcroForm is created and the signature is referenced there. In the document, which already contains the AcroForm, the dictionary is not updated accordingly. I also tried the build from flathub, which I guess is more recent than the one debian. It shows the same behaviour. -- You are receiving this mail because: You are the assignee for the bug.
