Running results in Broken pipe on Debian Linux

I tried both with Pack Only turned on and off, result is the same:

Python: Traceback (most recent call last):
  File "/home/muhuk/.config/blender/2.92/scripts/addons/blender_xatlas/__init__.py", line 329, in execute

    stdin.write(value)
BrokenPipeError: [Errno 32] Broken pipe

location: <unknown location>:-1

I'm on Debian Buster (stable), using Blender 2.92 official release and blender-xatlas 0.8.0.

$ ls -la ~/.config/blender/2.92/scripts/addons/blender_xatlas/xatlas/

The scene I am testing has a single object like this (already unwrapped using builtin algo):

Hi, thanks for reporting the issue.
I'll see if I can recreate it, and find out what's happening ASAP!

I've run the same test on Blender 2.93-beta and got this error:

Python: Traceback (most recent call last):
  File "/home/muhuk/.config/blender/2.93/scripts/addons/blender_xatlas/__init__.py", line 329, in execute
    Unwrap_Lightmap_Group_Xatlas_2.execute(self, context)

    obTest.obName = safe_dict[obTest.obName] #probably shouldn't just replace it
AttributeError: 'NoneType' object has no attribute 'obName'

location: <unknown location>:-1

I have also noticed that it triangulates my default cube.

This is the full output in the console:

Even if I choose multiple objects this line is never printed. I suspect xatlas-blender execution results in an error or empty response.
