Yes, I just discovered this.
Here is the patch:
diff --git a/gr-wxgui/src/python/plotter/gltext.py
b/gr-wxgui/src/python/plotter/gltext.py
index 67f62ca..617d123 100644

Once I changed this to wx.Colour, it didn't show the previous error. how ever,
now I get something related to the OpenGL rendering context:
$ python scopesink_gl.py
