This problem occurs when start date is the same day of month as the end date. So start date = Jan. 1, 2013 and end date = Feb. 1, 2013 will produce the error.
I've tracked down the problem to the 'latest.php' file in the module (folder default for correct line numbers). A check is made if DAYOFMONTH is the same for start and end (and the check thinks it is not multi-day). I've added a check on month and year (so same dayofmonth but different month or year is different).
