BUG:	When an output wavelength range is selected which does not overlap
	the input data and the output format is onedspec a segmentaion
	error occurs.  The correct warning message, 'No pixels to extract'
	is printed but then the error cleanup was not handled correctly.
	This problem does not occur with multispec output which is,
	therefore, a workaround.  However, it is likely that the wavelength
	range was accidentally set incorrectly since an operation outside
	of the data is probably not intended.  Note that the correct
	behavior is to not produce an output spectrum in this case.

STATUS:	Fixed for the next release.
