Bug#966174: okular: none
Dear Maintainer,
I could reproduce it with the state of Debian testing at 2020-07-24.
Upstream bugs seem to be these:
https://bugs.kde.org/show_bug.cgi?id=407338
https://gitlab.freedesktop.org/poppler/poppler/-/issues/766
The issue seems to be resolved since poppler 0.77 and above.
Kind regards,
Bernhard

Hi Miguel, hi all, > https://www.boe.es/boe/dias/2018/04/26/pdfs/BOE-A-2018-5704.pdf As a data point, on my system with okular 4:20.04.3-1~np1 frameworks 5.72 I don't see any crash, the document is opened, shown as signed, and shows information about forms. This is with the packages for KDE/Plasma/Frameworks from my repositories.
