Wrong. It is the new implementation of QGLWidget.renderText() confusing 
PyOpenGL error checking:

http://pyopengl.sourceforge.net/ctypes/using.html

Just adding a method to the previous code solves the problem.

     if qt.qVersion() >= '4.3.0':
         def renderText(self,  x, y, z, text, font):
             GL.glGetError()
             qt.QGLWidget.renderText(self, x, y, z, text, font)
             GL.glGetError()
