If you are viewing the logs of a job which only has a few lines of output, pressing the previous or next buttons will take you to a page with no output. Trying to navigate back (with those buttons) will not work. Prev/next buttons should either be disabled if there is no more information in the relevant direction(s) or ... something else sensible.
