[horde] Error while executing /usr/bin/horde-alarms

[Jens Grüntjes]

Hello,

I'm running the latest stable release (Horde Groupware 5.0.2). When I  
execute the script /usr/bin/horde-alarms (either via cron-script as  
the user that is running the webserver or manually as this user or  
manually as root) I get the following error in my log-file:

The alarms work anyway so it doesn't hurt but if everythings works  
normally those messages should not appear in the logs.

In Horde's conf.php I configured two admin users who can authenticate  
against the email-server

$conf['auth']['admins'] = array('admin1', 'admin2');

I tried the same with only one admin user but the error is the same.

Is this a bug in my configuration and if so where should I look first?
