aplpy/aplpy — Issue #45: problem with .show_grayscale() and .save()

The .show() and .save() functions don't work properly. Using the example code from the documentation, gc.show_grayscale() doesn't produce any plot at all (but returning Auto-set vmin/vmax), but if I execute matplotlib.pyplot.show() next, the plot comes up. Also, when I run the script
```import aplpy
gc = aplpy.FITSFigure('new.fits')
gc.save('myfirstplot.png')```
I get a plot only containng the coordinate axes but an empty white image. Is this a known bug and is there any solution?
I'm running Python2.7 on a Mint Linux 12 machine with gnome3, the latest versions of numpy, matplotlib, pyfits, and pywcs installed with python-pip.
