Dolphin Flatpak shows error when trying Open with Dolphin on desktop. Dolphin is launched but then a red banner is at the top that says "Unable to create io-slave. Unknown protocol 'desktop'.". It opens the directory "desktop:/" I have tried allowing all permissions in Flatseal and that did not produce a different result. STEPS TO REPRODUCE 1. Open dolphin 2. Right click on any file type (.ods, .png, etc) 3. Click on the File Type Options button under Type OBSERVED RESULT Dolphin does in fact launch, but a red banner is displayed at the top of Dolphin with the text "Unable to create io-slave. Unknown protocol 'desktop'." EXPECTED RESULT Dolphin is launched and no red banner at the top is displayed with the error string.
