Description Aayush Agarwal 2020-09-01 15:47:33 UTC 
SUMMARY

Okular is not loading print previews.

STEPS TO REPRODUCE
1. Open Okular
2. Load any PDF
3. File>Print Preview

OBSERVED RESULT

A window which says "could not load print preview part".

EXPECTED RESULT

A print preview of the PDF, based on my printer page layout.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: openSUSE tumbleweed 20200826 snapshot (Linux <host> 5.8.2-1-default (71b519a) x86_64 GNU/Linux)
KDE Plasma Version: 5.19.4
KDE Frameworks Version: 5.73.0
Qt Version: 5.15
okular Version: 1.11.0

ADDITIONAL INFORMATION

Opening okular from command line provided me a hint: org.kde.okular.ui: Could not find a PS viewer for the preview dialog.

When I tried to load a print preview for a .odt file, the preview loaded successfully. I don't have files in many different supported formats so I have not checked all of them.

I'm going to bet that someone at opensuse decided not to compile okular with ghostscript support, go and complain to them.

The security team suggested strongly to make the ghostscript plugin optional and not installed by default: https://bugzilla.opensuse.org/show_bug.cgi?id=1122797

There's the possibility to show a dialog if this case is detected, I'll start a discussion about that.
