"Failed to initialize any backend" in Nautilus on Fedora 32

I've been spending some time trying to get this to work with Nautilus on Fedora 32, and I've been having some difficulty. I copied the stl-thumb-mime.xml and stl-thumb.thumbnailer files into the proper directories, and it seems that the thumbnails are failing. I check ~/.cache/thumbnails and it confirms that stl-thumb is indeed failing.
I tried to run the program directly using the same arguments found in stl-thumb.thumbnailer, and it was a success.
Moving on from there I turned on debug logging in nautilus and enabled the full rust backtrace and I get the following:

I suspect something weird is going on with Gnome's sandboxing of thumbnailers. Can you also try running with the -vvv option and post the output from that?

I recompiled to remove some of my debugging code, and it reveals a different error.

This is the problem, in both cases.
WARN - Unable to create headless GL context. Trying hidden window instead.
Reason: NoBackendAvailable(LoadingError("LibraryNotFound { descr: \"libOSMesa.so: cannot open shared object file: No such file or directory\" }"))
We'll need to find out why libOSMesa.so is not available.

I had a similar problem on Fedora 33.
My backtrace after manually unpacking stl-thumb_0.3.1_amd64.deb and moving the files into place is.

creating a bwrap wrapper that removes --unshare-all makes thumbnails work but is probably not the wisest decision.
unlimitedbacon commented
It's working fine in Nautils 40 running on Arch.
For comparison, here is the bwrap command:
bwrap --ro-bind /usr /usr --ro-bind /etc/ld.so.cache /etc/ld.so.cache --symlink /usr//bin /bin --symlink /usr//lib64 /lib64 --symlink /usr//lib /lib --symlink /usr//sbin /sbin --ro-bind-try /var/cache/fontconfig /var/cache/fontconfig --setenv GST_REGISTRY_1_0 /home/neo/.cache/gnome-desktop-thumbnailer/gstreamer-1.0/gstreamer-1.0.registry --bind /home/neo/.cache/gnome-desktop-thumbnailer/gstreamer-1.0 /home/neo/.cache/gnome-desktop-thumbnailer/gstreamer-1.0 --ro-bind-try /etc/alternatives /etc/alternatives --proc /proc --dev /dev --chdir / --setenv GIO_USE_VFS local --unshare-all --die-with-parent --setenv G_MESSAGES_DEBUG all --bind /tmp/gnome-desktop-thumbnailer-HCC510 /tmp --ro-bind /home/neo/Code/stl-thumb/test_data/sphere.stl /tmp/sphere.stl --seccomp 12 stl-thumb -f png -s 256 /tmp/sphere.stl /tmp/gnome-desktop-thumbnailer.png
Arch has some gstreamer stuff in the command, but I don't see how that would make a difference.
Are you guys sure that you have the mesa-libosmesa package installed?
ssendev commented
mesa-libOSMesa is installed and when removing --unshare-all it does work.
I just did some testing and it appears replacing --unshare-all with --unshare-user-try --unshare-ipc --unshare-pid --unshare-uts --unshare-cgroup-try also works which means --unshare-net is the culprit.
unlimitedbacon commented
Ok. Networking should not be required for running OpenGL. I don't know enough about Bubblewrap to know what could be going on here. Its probably worth filing a bug upstream somewhere, although I'm not sure if that should be with Fedora or Bubblewrap.

hello :)
I am facing that same issue and i was wondering if they was a work around found ?
