SUMMARY I was playing around with the Dolphin settings to figure out another issue (no PDF preview), when I enabled the User Feedback from the Dolphin Preferences window. After I have saved with this enabled, Dolphin would crash on start. It was very hard to get back from this, in the end I deleted basically all KDE settings I could find in ~/.config, ~/.local etc and rebooted. Hence I have not tried to reproduce this yet. STEPS TO REPRODUCE 1. Enable User Feedback in Dolphin Preferences 2. Try to start Dolphin OBSERVED RESULT Crash with message: "Qt: Session management error: networkIdsList argument is NULL" EXPECTED RESULT Dolphin works with the User Feedback enabled. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro (available in About System) KDE Plasma Version: 5.22.5 (I think) KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2
I just noticed it looks like this is very similar to Bug 431730, however that one is marked as fixed in version 20.12.2, while I am running 21.
