Flatpak Okular silently crashes when opening signed PDF
Posted: Mar 3rd, '23, 12:04Hello, the title says it all, but I can be more specific. I'm on Mageia 8 (64 bits) and have installed Okular from both the regular repos and Flatpak (I needed the most recent version to digitally sign PDFs).
Both seem to run OK, but the Flatpak one silently crashes when opening digitally signed PDFs, whereas it can open non-signed PDFs just fine. There's no error message when clicking those PDFs in Dolphin, it just does nothing, but the regular version opens both just fine.
This is not urgent as the workaround is simply using the regular version, but I wonder how to find what causes this bug, and whether somebody else can reproduce it.
This is the regular version:
And this is the flatpak one:
I've tried to open a signed PDF with Flatpak Okular from the command line. It spits some errors, but when opening a non-signed PDF I get the same. The only difference is that only the non-signed PDF is successfully opened:
