xdg-open does not use default handler

[Linus Kardell]

I'm on OpenSUSE Leap 15.2 KDE, and if xdg-open with a directory (e.g. xdg-open ~) in a snap it opens the directory in Visual Studio Code, whereas if I run the same on the host, the directory is correctly opened in Dolphin. Presumably, this is related to this: https://github.com/microsoft/vscode/issues/41037, where it looks like the system takes the first entry, rather than the default entry.

When you run xdg-open inside a snap, it will try to check whether a portal is available and direct a request there.

Can you double check that the output of `xdg-mime query default inode/directory` lists dolphin desktop file? On top of that, can you check that xdg-desktop-portal is running?

Should I have removed the incomplete mark from this? The problem is still around.

This looks like a problem with xdg-desktop-portal:

sep 14 10:15:37 raven xdg-desktop-por[11828]: Failed to get application states: GDBus.Error:org.freedesktop.portal.Error.Failed: Could not get window list
sep 18 10:57:48 raven xdg-desktop-portal[11828]: Warning: 'sandbox' is not in the list of known options, but still passed to Electron/Chromium.

I would suggest trying to open a bug on opensuse bugzilla, might be something with xdg-desktop-portal actually.
