Created attachment 118396 [details] Infinite message boxes I don't know if it's Konqueror bug or KIO KRun component bug, but it only happens when Konqueror is installed. STEPS TO REPRODUCE 1. Install Konqueror 2. Go to System settings -> Default Applications -> Web Browser 3. Set 'with the following command' and *intentionally* set the wrong one ('abcdef' for example) 4. Launch some link from Konsole (or from some app that calls external web browser for links) 5. Get infinine 'Command not found' message boxes. The main point here is that if the command can't be found, default one will be lauched, which is Konqueror. If I delete Konqueror nothing like this happens. I had Firefox, Chromium and Konqueror installed when this happened. See attached video for example. Plasma 5.15.1 / Frameworks 5.55.0
