Description

Upon creation of an Event via the Calendar UI, an email notice is sent to the Originator and to each participant: behavior as documented.
Documentation says that reminder emails will be sent x minuites before the scheduled time of the event, as configured in number.minutes.reminder.send under the Admin>Configure UI.
While a reminder email is sent to the Organizer, none are sent to the participants. Also, the link in reminder that is sent is malformed, with a 'null' inserted where the hash for the event should be printing.

For a current value of 10 in number.minutes.reminder.send,
with [e-mail] as originator
and decoy, user1, user2, and user3 as participants here is the 'tail -n 20' of the mta log for such an outcome(exim4 under Jessie):
