[kronolith] Reminders only get sent to owner

See below, as far as I can tell this would satisfy that they have the
even reminder preference set:

horde=# select * from horde_prefs where pref_uid='userB' and  
pref_name='event_reminder';
  pref_uid | pref_scope |   pref_name    | pref_value
----------+------------+----------------+------------
  userB    | kronolith  | event_reminder | read
(1 row)

> and have an email address set in their identities set.

I'm assuming this is the identities that you define globally in horde?
If so, yes userB has an e-mail address set there.

horde=# select * from horde_prefs where pref_uid='userB' and  
pref_name='identities';
  pref_uid | pref_scope | pref_name  | pref_value
  userB    | horde      | identities |  
a:2:{i:0;a:11:{s:2:"id";s:16:"Default  
Identity";s:8:"fullname";s:12:"User  
B";s:9:"from_addr";s:20:"userB at domain.com";s:12:"replyto_addr";s:20:"userB at domain.com";s:9:"signature";s:0:"";s:9:"sig_first";i:0;s:10:"sig_dashes";i:0;s:14:"save_sent_mail";s:1:"1";s:16:"sent_mail_folder";s:9:"sent-mail";s:11:"private_key";N;s:16:"private_key_type";N;}    i:1;a:14:{s:16:"default_identity";s:1:"0";s:2:"id";s:3:"Alias";s:8:"fullname";s:12:"User  
B";s:9:"from_addr";s:17:"userBAlias at domain.com";s:12:"replyto_addr";s:17:"userBAlias at domain.com";s:10:"alias_addr";a:0:{}s:10:"tieto_addr";a:0:{}s:8:"bcc_addr";a:0:{}s:8:"mail_hdr";s:0:"";s:9:"signature";s:9:"UserBAlias";s:10:"sig_dashes";i:1;s:9:"sig_first";i:1;s:14:"save_sent_mail";i:1;s:16:"sent_mail_folder";s:9:"sent-mail";}}

This was working flawlessly up until a few weeks ago, and the
user's settings haven't changed and while I can't swear to it
(the user didn't actually mention this until later), I think it
happened at the same time we upgraded horde to 3.1.5.
