Created attachment 142358 [details] Secondary panel SUMMARY When you have a secondary panel (based on empty or application) with application desktop files and you click on the icon, it will try to open the file as a directory in dolphin. STEPS TO REPRODUCE 1. Create a new panel 2. Add a launcher widget 3. From the launcher right click on an application and select "Add to panel (widget)" 4. Go out of edit mode 5. Click on the icon on your panel OBSERVED RESULT Dolphin opens with the ~/.local/share/plasma_icons/<application>.desktop as the path. EXPECTED RESULT The application would start SOFTWARE/OS VERSIONS Windows: No macOS: No Linux/KDE Plasma: Artix Linux (available in About System) KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Kernel: 5.14.8 (64bit) Graphics: X11 (1.20.13) Gfx Driver: Nvidia (470.74) xdg-utils: 1.1.3+19+g9816ebb-1.1

I haven't changed any settings in plasma for a long while and the secondary panel worked while I used plasma-desktop 5.22.2. xdg is using the default system config which is provided by Artix (based on Arch Linux, just systemd replaced with Gentoo replacements). Yes, I have tried to create new panel and the result is the same.
Hmm, cannot reproduce with those steps on Plasma 5.23. Can you upgrade and give it another try?
Created attachment 142610 [details] plasma-org.kde.plasma.desktop-appletsrc Included my plasma-org.kde.plasma.desktop-appletsrc, removing it from .configure and re-login to plasma5 seems to made the panel to work. Still dolphin ain't working correctly, tried to delete the ~/.config/dolphinrc but still when clicking on a file, it opens a new tab instead of running the default application for the file type.

Created attachment 143563 [details] mimeapps.list Seems the thing that broke dolphin for me was the mimeapps.list, but I'm not sure which row causes the problem. Renaming the file made dolphin to work as expected.
x-scheme-handler/file=org.kde.dolphin.desktop would appear to be the culprit. Out of curiosity, would you be interested in commenting on why you're using PCManFM instead of Dolphin?
