If fiscal year is not 01/01/20xx to 31/12/20xx (french date) you get the error
Error occurred while validating the field(s) date_stop: Error!
The period is invalid. Either some periods are overlapping or the period's dates are not matching the scope of the fiscal year.

error is not the same if you install fiscalyear from 01/10/2012 to 30/09/2013
