When Dolphin is set to open archives as folders and you click to open an archived file then click on a text file within an archive then kwrite/kate opens as a blank new file. Reproducible: Always Steps to Reproduce: 1. Set Dolphin to open archive as folders 2. Click on an archived file ie tar.gz/zip 3. Click on a text file within the archive 4. Kate/Kwrite opens blank new file Work around to use pluma/scite/leafpad or another text editor.
I can confirm this behaviour
Works for me with Kate. Moving to Kate component for further investigations.
Tried with Dolphin + Kate and KWrite from 18.04 release, works.
