image colors wrong on GTK Cairo

I just noticed all of the image and colorbar colors are wrong in
GTKCairo (on linux). When I tried to test on the pure Cairo backend,
I get

peds-pc311:~/python/projects/matplotlib/examples> python -dCairo Traceback (most recent call last):
  File "", line 25, in ?
  File "/usr/local/lib/python2.3/site-packages/matplotlib/", line 712, in savefig
    return fig.savefig(*args, **kwargs)
  File "/usr/local/lib/python2.3/site-packages/matplotlib/", line 457, in savefig

  File "/usr/local/lib/python2.3/site-packages/matplotlib/backends/", line 583, in _save_png
    ctx.set_target_png (fileObject, cairo.FORMAT_ARGB32, width, height)
