Comment 1 Patrick Silva 2022-11-14 17:15:33 UTC

EXPECTED RESULT:
Dolphin should not break the 'Open containing folder' feature of internet browsers on Gnome

Comment 2 Nicolas Fella 2022-11-14 19:10:01 UTC

The reverse is also the case. Installing Nautilus on Plasma breaks Dolphin from being opened. It's kind of a fundamental flaw of the org.freedesktop.FileManager interface. It's undefined which implementation gets activated if there are multiple

Comment 3 Patrick Silva 2022-11-14 19:36:09 UTC

I have Nautilus on my Arch Linux that runs Plasma 5.26.3. Nautilus instead of the default Dolphin opens.
Possibly this bug is a duplicate of bug 397953

Comment 4 Nate Graham 2022-11-15 18:46:30 UTC

Yep.

It's for this reason that on Fedora, they have a daemonized Dolphin instance constantly running in the background when you're in a Plasma session, so it will prefer the already-running app and always give you Dolphin.
