OBJ files don't load textures in pymeshlab >2022.2

[bedaberner]

When running the following code I get the expected result in pymeshlab 2022.2 and before.
However in later versions, the textures don't seem to be imported (no textures are copied to the output folder and the .mlp file contains only the mesh, no textures.)

import pymeshlab

ms = pymeshlab.MeshSet()
ms.load_new_mesh("example.obj")
ms.save_current_mesh("output/result.obj", save_vertex_color=True,save_vertex_normal=True,save_face_color=True,save_wedge_normal=True,save_polygonal=True,save_textures=True,texture_quality=-1)
ms.save_project("test.mlp")

I cannot replicate the issue. When saving a mesh, also the texture is saved in my system and in my input mesh.
The mlp file not containing the textures is expected, since textures are associated with the mesh.
Could you please share your input file and your system setup?

It stops working from v2022.2.post3.

I have a similar issue, also stops working after v2022.2.post2 (last working version).

Using Set Texture filter, this is the error:

Traceback (most recent call last):

I am able to load meshes fine in the GUI. When I load from python, I keep seeing it replaced with "dummy.png", and without yet having taken a detailed look at the pybind11 bindings, can't for the life of me work out why some load fine and others do not.

Have tried 2023.12.post2 and 2023.12, which matches the flatpak I have installed. This affects GLB/GLTF too.
