    Description

      OpenGL geometry shaders are not working when used the new Qt 5.1 classes: QOpenGLShaderProgram and QOpenGLShader.

      See attached code.
      In hellowindow.cpp line 175, glGetError returns 0x502 (invalid operation).

      But if I try to use the obsolete classes (QGLShaderProgram and QGLShader), it is working correctly (no error returned by glGetError)! (un)comment the lines in hellowindow.h for test...
