Short description of error
Blender crashes with segfault when trying to import a model using blender --python-expr when the startup file or the opened file has an asset browser open.

Exact steps for others to reproduce the error
Download sample model from KhronosGroup github.

Run blender with:

blender <path/to/file/with/asswet/browser/open> --python-expr 'import bpy; bpy.ops.import_scene.gltf(filepath="/<PATH>/Sponza.gltf")'

Blender crashes with the follow stack trace:

I'm not able to reproduce this issue using the latest build of 3.3.0. The model gets imported correctly and there's no indication of an issue:

./blender --python-expr 'import bpy; bpy.ops.import_scene.gltf(filepath="/home/jesse/source/fx-gltf/test/data/glTF-Sample-Models/2.0/Sponza/glTF/Sponza.gltf")'

Data are loaded, start creating Blender stuff
glTF import finished in 1.64s

If blender is crashing, it may write out a file like so. Is there a *crash.txt file in your /tmp directory that corresponds to the crash you are seeing?

Unsure what's going on but that crash file is the old one; the version it prints out is the one from a few days ago: # Blender 3.3.0, Commit date: 2022-06-28 22:57, Hash c0e453233132

Will set back to Needs Triage in hopes that someone else might be able to confirm the issue.

Can't reproduce myself either. Does moving the file somewhere else before importing makes a difference?

Can you try with blender --factory-startup --python-expr 'import bpy; bpy.ops.import_scene.gltf(filepath="/home/workstation/Desktop/glTF/Sponza.gltf")'? That is, with factory setup.
It seems to me that this code path only executes when there is an asset browser editor open. Maybe your startup file have one opened?

Very astute! My startup file does have an asset browser editor open and running blender with --factory-startup produces no error and the gltf file gets imported as expected. We seem to have this narrowed down. Thank you!

Cannot reproduce (not even in c0e4532331 as reported here and with a file with an asset browser open).

Can you re-check if this is still a problem in fresh builds from https://builder.blender.org/download/daily/ ?
