gjs-console crashed with signal 6 in g_assertion_message("assertion failed: (!priv->is_realized)") from g_assertion_message_expr() from gsk_renderer_dispose() from gsk_renderer_dispose() from g_object_unref()

[Maxim Solodovnik]

Test Case
---------
1. From Ubuntu 22.10, install Lunar's glib 2.76.1
2. Log out
3. Log back in
4. Open the GNOME Shell Activities Overview and type the word smile
5. Close the Activities Overview

What Happens
------------
In my case, if I repeat 4 and 5 several times, I will eventually get an apport crash popup dialog reporting that the GNOME Shell search provider for GNOME Characters has crashed.

Tracking In

Other Info
----------
This isn't a gjs bug, but I'm leaving the gjs task open since I think apport looks for it.

Status changed to 'Confirmed' because the bug affects multiple users.

[AndreK (andre-k)]

seeing this on Ubuntu 23.04

[Pavel Selivanov (muiriled)]

I'm getting this error every time I'm launching Steam (deb version).

[Jeremy Bícha (jbicha)]

I'm dropping the Kinetic tasks since we don't support glib 2.76.1 on Kinetic.

[Marco Trevisan (Treviño) (3v1n0)]

I think this should improve the situation https://gitlab.gnome.org/GNOME/gnome-characters/-/merge_requests/92

[Shy Zedaka (shaytzedaka)]

Had this aswell on a fresh install of Ubuntu 23.04 Beta.

[Launchpad Janitor (janitor)]

This bug was fixed in the package gnome-characters - 44.0-2

---------------
gnome-characters (44.0-2) experimental; urgency=medium

  * debian/patches: Do not crash when rendering invisible characters
    (LP: #2012287)
  * debian/control: Add build-dependencies on xvfb and gjs for testing
