Unable to authenticate with smartcard: gnome-shell throws on unhandled promise rejection

[Kyle Metscher]

Upstream report: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/7526

Opening as part of response to support ticket.

After boot, GDM does not prompt for smartcard authentication correctly. It is possible to strike Esc and get GDM to prompt for a username and a smartcard PIN from the initial locked-out state, but this does not start a new desktop session and instead hangs. Striking Esc allows for the login to be attempted again, but with the same results.

Syslog entries include unhandled promise rejections from the onSessionOpened event in loginDialog, and perhaps more importantly also from the user verification stack that is used to create the initial authentication options prompt (stack traces of the syslog entries attached).

Affects GDM 46.0-2ubuntu1 in Noble.

To reproduce, configure smartcard auth for a network user on a new Noble install and try to sign in.
