Description matthias.schrumpf 2021-04-16 07:31:10 UTC 
SUMMARY
Some folder picking dialogs within applications do not allow folders as input. They will show no files to pick, but "Open" does nothing. 

STEPS TO REPRODUCE
For example, 
1. Open Firefox
2. Go to the standard download folder option in the settings
3. Click "Browse" and attempt to select a different folder.

OBSERVED RESULT
It is not possible to select a folder in the dialog. 

EXPECTED RESULT
It should be possible to select a folder in the file picking dialog. 

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: 5.9.16-1 Manjaro
KDE Plasma Version: 5.21.3
KDE Frameworks Version: 5.80.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION 
Firefox has Plasma integration installed and the string /usr/lib/firefox/firefox %u as the command in the application settings menu to force it to use the Dolphin file picker. This problem comes up in many other applications as well.

What are these many other applications?

Moving bug to portal for now since the firefox example might be a problem with the portal unless this also happens with native apps, then I guess KIO is to blame.

Thank you. 
Just quickly scanning through my list of installed applications, Thunderbird, Telegram and Chromium have the same problem. They all have an option to set a standard folder path for downloads/received files. The file picker dialog will open, showing only folders and no files. It is possible to open folders, but not to select them. So one is always stuck with the preset folder.

Conceivably they could all using the portal. At least for firefox I can reproduce the problem.
