Following the advice to ping you on the mailing list, I've submitted a suggestion for a patch to the EMF Backend. I've copied the contents here for convenience.
Patch ID is: 3232997 Content is: With Matplotlib 1.0.1, When plotting a patch (e.g. text with a bbox with facecolor), the facecolor of the patch is passed to the backend as RGBa. EMFBrush can't handle RGBa and dies with the following: File "/usr/local/lib/python2.7/dist-packages/matplotlib/patches.py", line 411, in draw renderer.draw_path(gc, tpath, affine, rgbFace) File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_emf.py", line 260, in draw_path self.select_brush(rgbFace) File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_emf.py", line 567, in select_brush brush=EMFBrush(self.emf,rgb) File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_emf.py", line 107, in __init__ r,g,b=rgb ValueError: too many values to unpack Suggested patch is to change line 107 in backend_emf.py from r,g,b=rgb to: r,g,b=rgb[:3] which will drop the alpha channel. Given the EMF backend doesn't support alpha channels, it shouldn't cause any problems to do this silently. ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
