Hi,

When trying to save a figure in format 'png', Octave crashes.
This is from an almost clean installation of Ubuntu 15.10.
Octave crashes both when ran with GUI and without.
Below is a very short sequence that crashes Octave for me.
In essence it's:
  fig=figure(1); peaks(); saveas(fig, 'test.png', 'png')

I suppose it'd be ok that saving as PNG doesn't work because some tools are
missing, but it shouldn't crash Octave in my opinion.

Regards,
Christian
