Texture loading from file crashes kivy without exeption -- (when loading atlas)

[bela127]

Software Versions

• Python: 3.12.4
• OS: Win11
• Kivy: 2.3.0
• Kivy installation method: pip

Describe the bug Kivy crashs (without showing any error) when loading a "kivy.atlas.Atlas". (The Bug is probably not Atlas related but a general bug with Image loading)

I tracked down the source of the Bug quite far, it originates in the Texture loading process when "Texture.create_from_data" is called in "ImageLoaderBase.populate()" .

[Texture == kivy.graphics.texture.Texture] Sadly i could not debug Texture because it is cython code, so you have to find the bug in there ;)

Expected behavior No crash.

To Reproduce

import kivy
kivy.require('2.3.0')
from pathlib import Path

from kivy.logger import Logger, LOG_LEVELS
Logger.setLevel(LOG_LEVELS["debug"])

from kivy.atlas import Atlas

from kivy.app import App
from kivy.uix.button import Button

class MyApp(App):

    def build(self):
        Logger.warning(kivy.__version__)
        kivy_data_path = Path(kivy.kivy_data_dir)
        Logger.warning(kivy_data_path)
        atlas_path = kivy_data_path / "./images/defaulttheme.atlas"
        Logger.warning(atlas_path)
        atlas = Atlas(str(atlas_path.as_posix()))
        #Logger.warning(atlas.original_textures)
        return Button()

if __name__ == '__main__':
    MyApp().run()

I am getting the same issue Used the same logger enabled script that bela127 created. Final commands

    atlas = Atlas(atlas_path)
    Logger.warning("Atlas loaded")
    Logger.warning(atlas.textures.keys())

On loading the first atlas png file [DEBUG ] [Atlas ] Load [DEBUG ] [Atlas ] Need to load 2 images [DEBUG ] [Atlas ] Load [DEBUG ] [ImageSDL2 ] Load <C:\Data\PyProjects\BPCTst\icons-0.png>

The kernel died, restarting...
