Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Installing the package `phonon4qt5-backend-vlc` fixed the crash for me. It should be in Elisa dependencies.

This issue is still present in Kubuntu 22.10. Running strace on Elisa points to some possible missing dependencies.

Installing vlc-plugin-base allows Elisa to work properly.

It seems, while installing Elisa installs libvlc and libvlccore, it doesn't install the vlc-plugin-base needed for it to run properly.

Version affected: Kubuntu 22.10
Elisa version: 22.08.3-0ubuntu1~ubuntu22.10~ppa
Expected: Not to crash on startup
What happened: Crashed on startup

Steps to reproduce: Run Elisa.
