Page crashes when opening web inspector

Technical information:


Epiphany (GNOME Web) version: 48.0
WebKitGTK 2.48.0
GStreamer 1.24.12
GTK 4.18.2
Libadwaita 1.7.0
Distributor: GNOME
Operating System: Debian GNU/Linux 12 (bookworm) x86_64
Flatpak version: 1.14.10

Whenever I try to inspect a page (any web page), the page crashes (image attached with the crash).

Already reported this to GNOME Web, but it was marked as an issue with WebkitGTK: https://gitlab.gnome.org/GNOME/epiphany/-/issues/2613

CLI shows the following text:

MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:782: FINISHME: support YUV colorspace with DRM format modifiers
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:814: FINISHME: support more multi-planar formats with DRM modifiers
VM 0x7f853d40a000 on pid 2 received NeedDebuggerBreak trap

(epiphany:2): epiphany-WARNING **: 00:10:46.346: Web process crashed

Thanks for taking the time to report this issue. Unfortunately, without a stack trace from the crash it's very hard to know what caused it. Please see https://handbook.gnome.org/issues/stack-traces.html for more information on how to provide a stack trace.

Stack trace of the Webkit GTK crash

I followed the instructions for flatpak reporting as noted here:

https://handbook.gnome.org/issues/stack-traces.html

Hello, I just added the stack trace as an attachment

[Philippe Normand]

Looks like an host issue, probably related with misconfigured dbus or a11y. Is this in GNOME or some other desktop session?

I'm using GNOME 43 running Wayland

[Philippe Normand]

That's the assert, afaict, RELEASE_ASSERT(!m_isConnecting) in AccessibilityAtspi::registerObject().

I cannot reproduce this here on F42 (GNOME).

Is there anything I can do to help you reproduce the bug?

Sorry, I can indeed reproduce this. I'm not very familiar with atspi though, not sure I can help much :(

[Philippe Normand]

Is this still happening David? I cannot reproduce it here anymore, but I think it's a race condition...

It looks like AccessibilityAtspi::registerObject() is called before the dbus async name ownership claim completed (m_isConnecting is set to false in AccessibilityAtspi::didOwnName())... Georges, can you take a look please?

I run WebKitGTK 2.48.2 with GNOME Web 48.3 (GStreamer 1.26.0, GTK 4.18.5, Libadwaita 1.7.2) on NixOS and the issue still occurs.

The browser tab crashes both with the Inspector and when browsing regularly. Epiphany logs "Web process crashed" in the terminal when this occurs.

[Peter Bittner]

I might need to withdraw my report above from 3 days ago.

I've not seen any crash on the same WebKitGTK 2.48.2 based GNOME Web 48.3 browser anymore.

[Philippe Normand]

It's a flaky crash according to comment 10, so sometimes it will happen and sometimes not.
