      While working on MDL-41979, when I clicked on the Reports tab as an Administrator after attending a SCO having provided status, time and score, no data is returned and I've found the 3 warnings below, in the web server error log:

      [Tue Oct 29 23:07:52 2013] [error] [client 192.168.0.202] PHP Warning:  Division by zero in /path/to/moodle-master/lib/graphlib.php on line 1021, referer: http://hostname/moodle-master/mod/scorm/report.php?id=88&mode=graphs

      The same applies when clicking on the Graph report subtab: the image is missing and the warning are equal except for the missing of referer info.
