BUG:	When an error, such as invalid parameters or missing images, occurs
	the task first does some error clean up operations before reporting
	the error.  The problem with this is that the actual error message
	can get lost and a misleading message, such as environment variable
	or image header parameter not found, will be given.  Avoid this
	requires a code change.  One way to sometimes get to the true error
	is to eliminate the misleading error by setting a value for the
	missing evironment or header parameter.  Also check carefully all
	the task parameters since most error are the result of problems
	with them.

STATUS:	The error handling will be improved in the next release.
