Bug description:
I'm having trouble with a combination of NVIDIA + Python + Qt +
Opengl.
I tried using a QGraphicsView on a QGLWidget. I'm getting a white window and errors like this these:
QGLShader: could not create shader
Vertex shader for simpleShaderProg (MainVertexShader &PositionOnlyVertexShader) failed to compile
This is an example application triggering the problem:

The 'same' program works flawlessly when using C++/Qt. I'm seeing the exact behavior when using PySide instead of PyQt4 by the way. I'm also seeing this error when trying the original demo application from python-qt4-doc. Also, calling
QtGui.QApplication.setGraphicsSystem("opengl")
produces the same errors.
I'm experiencing this problems on 11.10 and 12.04 with the ubuntu-
provided nvidia drivers (where 12.04 includes the most recent driver
for now). After installing the driver using the original NVidia
installer, the applications work as expected.
