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.

Description Oliver Falk 2020-06-09 11:14:04 UTC 
Description of problem:
When switching the user, we see error messages from gnome-shell


Version-Release number of selected component (if applicable): -


How reproducible: Always.


Steps to Reproduce:
Vanilla RHEL 7.8 with Gnome.
1. Click on switch user
2. Check the messages - you see something similar to this:

    gnome-shell[<pid>]: g_array_unref: assertion 'array' failed

or this:

    gnome-shell[<pid>]: _st_paint_shadow_with_opacity: assertion 'shadow_pipeline != NULL' failed

or this (looks like being caused by some extension...):

    gnome-shell[<pid>]: JS WARNING: [resource:///org/gnome/shell/ui/popupMenu.js 717]: reference to undefined property "_delegate"
    gimp gnome-shell[<pid>]: JS ERROR: TypeError: super._onDestroy is not a function

    gnome-shell[<pid>]: clutter_actor_get_parent: assertion 'CLUTTER_IS_ACTOR (self)' failed

On some systems, the following can be seen in addition:

    journal: JS WARNING: [resource:///org/gnome/shell/ui/main.js 315]: reference to undefined property "MetaStage"
    journal: JS WARNING: [resource:///org/gnome/shell/ui/layout.js 221]: reference to undefined property "MetaWindowGroup"
    journal: JS WARNING: [resource:///org/gnome/shell/ui/osdMonitorLabeler.js 59]: reference to undefined property "MetaDBusDisplayConfigSkeleton"
    journal: JS WARNING: [resource:///org/gnome/shell/ui/slider.js 38]: reference to undefined property "CallyActor"
    journal: JS WARNING: [resource:///org/gnome/shell/ui/layout.js 29]: reference to undefined property "MetaWindowX11"
    journal: JS WARNING: [resource:///org/gnome/shell/gdm/realmd.js 130]: reference to undefined property "_loginFormat"

Actual results: Errors in the log files, which is an unwanted behaviour for my customer.


Expected results: No errors are logged under normal circumstances, esp. for normal actions like switching user.


Additional info:
Customer case attached.

That sounds like https://bugzilla.redhat.com/show_bug.cgi?id=1578186, although that was fixed in RHEL 7.8.


>     gnome-shell[<pid>]: _st_paint_shadow_with_opacity: assertion
> 'shadow_pipeline != NULL' failed

I only see one place where the pipeline is passed without a previous check, so that should be easily fixable.


>     gnome-shell[<pid>]: JS WARNING:
> [resource:///org/gnome/shell/ui/popupMenu.js 717]: reference to undefined
> property "_delegate"
>     gimp gnome-shell[<pid>]: JS ERROR: TypeError: super._onDestroy is not a
> function

That's https://bugzilla.redhat.com/show_bug.cgi?id=1782102

Those are javascript-encounters-non-introspected-subtypes warnings that cannot be fixed in gnome-shell. See https://bugzilla.redhat.com/show_bug.cgi?id=1751121.

Comment 3 Florian Müllner 2020-06-09 18:36:31 UTC 
For the sake of simplicity, one "Various JS warnings" bug is enough; let's track the bits that haven't dedicated issues yet in #1751121.
