Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

The problem is in frame 11:

(gdb) f 11

176         JS::RootedObject js_obj(cx, priv->wrapper());
(gdb) p priv
$6 = (ObjectInstance *) 0x0

  Checking for user environment and possible reproducer, this reproducer was found:

1. Login as any user choosing GNOME Classic in gdm prompt
2. As root run 'authselect apply-changes'

  User was told to use 'GNOME Standard', but almost certain will loose features as
user is also using gnome-shell-extension-desktop-icons
Comment 1 Florian Müllner 2023-02-15 14:55:07 UTC 
This looks like https://gitlab.gnome.org/GNOME/gjs/-/issues/510 (avoid crashing under these circumstances) and https://gitlab.gnome.org/GNOME/gnome-shell-extensions/-/issues/416 (window-list extension handling all settings changing all at once (due to `dconf update`).

It probably makes sense to include both fixes, but as they happened in different components, I reckon we'll need to separate bugs.

Let me change the component for this bug to gjs and copy the bug for gnome-shell-extensions.
