Comment 5 for bug 1917960

same session as my comment #2
(note I'd not use a GUI to do this, so cannot rule out errors on my behalf)

- created a new archive "archive.test.tar.gz" using lxqt-archiver
- when I try to add a text file (this time 'ubuntu_bugs-my-responses.txt') I again get two error boxes open up

Error: Failed to execute the command
Error: Archive not found

Note this is a closer test to what @lynorian did
