This is a bug although not one that I was aware of. R2008a reports an
error instead of seg faulting when you try this (message saying the JVM
is not running)

The same issue would occur if you use MATLAB's   print   command instead
of saveas.

The process is attempting to access a preference setting and that makes
use of the jvm.

Setting the figure's  'paperpositionmode'  property to 'auto' may
prevent the crash from occurring and allow the file to be created.
   set(gcf, 'paperpositionmode', 'auto');
