Subject: python-opengl: OpenGL.Tk package segfaults at import

Package: python-opengl
Version: 2.0.1.08-5
Severity: grave
Tags: patch
Justification: renders package unusable

The OpenGL.Tk package in python-opengl segfaults at import.

The problem goes away when the following patch is applied, causing the
Togl extension to Tcl to build without the "stubs" mechanism:

[Careful: the file has DOS-style line endings, and so the patch above
includes carriage return characters. I also just noticed that the patch
is against the wrong version of PyOpenGL, but the version of the file in
2.0.1.08 is essentially identical]

I can't tell whether this is really a tcl or tk packaging bug or a
PyOpenGL/Togl bug. Simple programs intended to test USE_TCL_STUBS
succeed, rather than segfaulting.

The same problem exists on at least Fedora Core 2 and Mandrake 10, and
has been reported upstream:
