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.

Fixed upstream in https://gitlab.gnome.org/GNOME/gnome-shell/-/commit/ea5aaa8ab2e386b59cd28f1266d4712194c97dcc.
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.
