Dear Maintainer,
I tried to create an archive ba selecting various folders in my homedirectory and then selecting "compress" in context menu.
In the appearing file-roller-box I selected to create a 7z- or ZIP-archive without further archivingoptions.
The archiving-process begins and a hidden folder is created during this. After this is completed the tempfolder is deleted, but no 7z or ZIP-archive is created.
I tried exactly the same using tar.gz and rar (which I have also installed and registered) as target archive formats and these produce the expected archives.
I hope these additional facts (some target formats are working, some not) helps pinpointing the error!
Thanks for investigating and correcting!
