SUMMARY If I try to open PDFs from an Android device connected via USB, I get this error in Okular: Could not open mtp:/Pixel 7a/Belső közös tárhely/Download/06_Functions.pdf. Reason: Unable to create KIO worker. Unknown protocol 'mtp'. Opening text files in Kate causes the same: Unable to create KIO worker. Unknown protocol 'mtp'. Opening images makes Gwenview display the loading gear endlessly. Opening .doc works in Libreoffice so I'm not 100% sure this is the right place for the bug. Opening videos with Haruna works, a "Copying..." Dolphin notification is displayed.
