I am using pcmanfm-qt on plasma-desktop and it doesn't open any apps when you click on a file. Videos don't open in vlc, etc. When I right click to "open with..." the menu is empty and in the file operations dialog I can't set the default application, either.
The mime types are configured in the system settings panel correctly.
I'm not sure if I missed something during install or this functionality doesn't work yet.
