Error on Associate Emails screen

[Rusty Nejdl]

We are running the 1.6.1 version of eventum and today we started to
receive the following error message when going to the Associate Emails
screen (emails.php):

Fatal error: Cannot use object of type PEAR_Error as array in
/usr/local/www/data/eventum/include/class.mail.php on line 230

I tracked this down to this line 1077 in class.support.php:

$res[$i]["sup_to"] =
Mime_Helper::fixEncoding(Mail_API::getName($res[$i]["sup_to"]));^M

When I comment this line out, the page displays correctly without any
error message and from what I can tell, no lack of functionality.

Has anyone else seen this error message and any ideas on how to proceed to
fix this in a more correct fashion?

Thanks!
