Bug description

Nemo freeze for 15 -30 seconds on opening when a VPN is connected.
Looking at the difference in the log with and without vpn active, it seems related to attempts to connect samba share:

Nemo-Share-Message: 20:49:43.896: unknown format for key 'Alia/usershare_acl' as it contains 'S-1-1-0:F,'.  Assuming that the share is read-only

Those message do not appear when the vpn is disconnected, and nemo opens instantly

Steps to reproduce

Have samba and nemo-share installed
Connect a vpn.
Have a couple of local folders/disks shared and mounted when nemo open.

Expected behavior

open nemo without freeze

Additional information

whatever vpn connected produce the same issue.
Another possibility is related to this first message which is displayed both with and without vpn connected:

** (nemo:47257): WARNING **: 21:02:46.712: Current gtk theme is not known to have nemo support (Catppuccin-Mocha-Standard-Pink-Dark) - checking...

Is the checking part happening on internet ?
