pyglet Segmentation faults and other errors

Question

I'm attempting to load images for sprites using the Python library pyglet. The original purpose was game-related, but I believe I have distilled the issue down to a single line of code. In the Python shell, I import pyglet, and then I run this line of code (or something equivalent):

pyglet.image.load("image.png")

Python quits, and the terminal outputs:

Segmentation fault (core dumped)

Sometimes it doesn't do this, though, and instead throws

Traceback (most recent call last):
  File "/usr/lib/python3.4/site-packages/pyglet/__init__.py", line 351, in __getattr__
    return getattr(self._module, name)
AttributeError: 'NoneType' object has no attribute 'load'

During handling of the above exception, another exception occurred:

    raise gl.ContextException('Could not create GL context') 
pyglet.gl.ContextException: Could not create GL context

or

Traceback (most recent call last):
  File "/usr/lib/python3.4/site-packages/pyglet/__init__.py", line 351, in __getattr__
    return getattr(self._module, name)
AttributeError: 'NoneType' object has no attribute 'load'

    from pyglet.gl import gl_info
ImportError: cannot import name 'gl_info'

(I'm not sure why it alternates between these two.)

In addition,

pyglet.window.Window()

also throws the exception

  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.4/site-packages/pyglet/window/xlib/__init__.py", line 166, in __init__

    raise gl.ContextException('Could not create GL context') 
pyglet.gl.ContextException: Could not create GL context

when run from the shell. Sometimes it runs when run from a file (it'll run, fail on subsequent runs, and then eventually work for another run), and if I remember correctly it runs without issue from a Python program frozen with cx_Freeze.

I haven't managed to find anything newer than a couple years old on Google. I don't know much about OpenGL; at present I use pyglet because of how it simplifies building apps.

I'm running 64-bit Manjaro Linux with XFCE, an AMD CPU, and an AMD integrated graphics card (with the closed Catalyst drivers). I have Python 3.4.2 and pyglet 1.2.0.

Any ideas?

Now (2016.10.30) this issue is fixet. On the website development present report about it.

Pyglet website developers is an example of image loader: http://www.pyglet.org/doc/programming_guide/image_viewer.html.

In the my Archlinux system (Linux alw 3.19.1-1-ARCH #1 SMP PREEMPT Sat Mar 7 20:59:30 CET 2015 x86_64 GNU/Linux) this error persist - core dumped with the python-3, bat work fine with the python-2. I am used newest version of the pyglet - 1.2.2.

On MS-Win 8.1 this example works without any errors. I think the problem is in the wrong job this module.

I am reported about this bug on the development site https://bitbucket.org/pyglet/pyglet/issue/25/core-dumped-on-linux-64

Now you can use only PNG format:

...
from pyglet.image.codecs.png import PNGImageDecoder

fname = 'pennant.png'
img_pennant = pyglet.image.load(fname, decoder=PNGImageDecoder())
...

This code not core dumped.
