Pass by reference error

[Jon Parise]

I get this when I attempt to send mail after the PEAR Mail.php
changes:

Fatal error: Only variables can be passed by reference in
/usr/local/apache/htdocs/horde/imp/compose.php on line 681

It looks like this occurs at the call to PEAR::isError, which wants a
reference.  I'm not sure what's going wrong here, but it doesn't look
like the $mailer->send() call on line 681 is returning a variable but
rather a static value.
