xdg-open without sudo do an error

[pandaroux007]

Good morning,
In a Python application (Flatsweep) I saw the use of a command ( xdg-open) allowing to open the default application for several file format, as well as for example the file manager .

However if I launch the XDG-OPEN "/" command to open my file manager at the root of my system (Linux Mint 22.1 Cinnamon), this opens the file manager but I have this error:

user@myPC:~$ xdg-open "/"
user@myPC:~$ 
(nemo:333560): Gtk-WARNING **: 14:48:51.561: Theme directory  of theme Vanilla has no size field

Nemo-Share-Message: 14:48:51.851: Called "net usershare info" but it failed: « net usershare » a retourné l'erreur 255 : net usershare: cannot open usershare directory /var/lib/samba/usershares. Error Aucun fichier ou dossier de ce nom
Please ask your system administrator to enable user sharing.

sys:1: Warning: g_object_weak_unref: couldn't find weak ref 0x71aa6f2ef510(0x5ad4ea411200)
^C
user@myPC:~$

The part sys:1: Warning: g_object_weak_unref: couldn't find weak ref 0x71aa6f2ef510(0x5ad4ea411200) appears when I close the window manager window (Nemo in my case because I am under Mint), but The command continues after that, I have to use Ctrl+C as indicated by the "^C" at the bottom...

But if I launch the command sudo xdg-open "/", Nemo opens well in high privileges mode, but the command ends directly, without this warning!

I wanted to post this bug at freedesktop but they are under gitlab and I can't even create an account on it 🥴

Tell me if information is missing, I gladly give it!
Sincerely,
Pandaroux007

There's no problem here - you get the same behavior just running nemo /.

I believe the g_object_weak_unref warning only occurs when closing a 'list view' style window - running nemo/xdg-open with sudo ends up applying the 'default' view settings to the location (which is the icon view). It can be safely ignored.
