[kronolith] Add/Delete event throws error

[Graeme Fowler]

Kronolith CVS HEAD (checked out this morning)
Horde 3.0.3

If I create or delete an event, with myself as sole attendee *or* with
additional attendees, committing the event or confirming deletion throws an
error like the one following (this from a deletion):

Warning: Illegal offset type in $PATH/horde/kronolith/lib/Kronolith.php on line
1081

Warning: Illegal offset type in $PATH/horde/kronolith/lib/Kronolith.php on line
1082

Warning: Cannot modify header information - headers already sent by (output
started at $PATH/horde/kronolith/lib/Kronolith.php:1081) in
$PATH/horde/kronolith/deleventaction.php on line 77

Adding in a debug log statement immediately prior to that bit of code like this:

        foreach ($share->listGroups(PERMS_READ) as $group) {
            foreach ($groups->listAllUsers($group) as $user) {
+++                Horde::logMessage(sprintf('Group: %s, User: %s, Calendar %s,
recipients: %s', $group, $user, $calendar, $recipients[$user]), __FILE__,
__LINE__,  PEAR_LOG_DEBUG);
                if (!isset($recipients[$user])) {
                    $recipients[$user] = Kronolith::_notificationPref($user,
'read', $calendar);
                }
            }
        }


...results in the following:

I have no groups defined at all. Something tells me, from looking at these
errors, that while it loops it's finding an array instead of a string in the
$user variable and that's making it chuck a wobbly.

Anyone else seeing anything similar? Can I post anything else to help?

For the record, the event gets added correctly and deleted correctly.
