Fix bug # 691532. Do not attempt to clone an image that does not exist, each completed page should have an associated image. We'd like to handle this corrupt file with a better fix, for example the absence of an end page segement is clearly a problem with respect to the specification, but Adobe and Artifex have chosen to support other "off spec" streams so more subtle and less obvious error checking is needed. Thanks to Tim Waugh for analysis on this problem.
