Bug#851214: images attached to emails are embedded with task=1 instead of task=mail

[Matt Carter]

Package: roundcube-core
Version: 0.7.2-9+deb7u5

When an image is attached to an email and a preview is displayed under 
the email body the image is included using a link such as

https://webmail.mysite.net.au/?_task=1&_action=get&_uid=9170&_mbox=INBOX&_part=2
which results in a broken image and roundcube throwing a 501 service not 
available

this was fine in deb7u2
the offending code in deb7u5 is the extra 'true' on line 93 of 
rcube_message.php
when this is removed the images display correctly as they did before


"/usr/share/roundcube/program/include/rcube_message.php" line 93 of 748

            'get_url' => rcmail_url('get', array(
                //'_mbox' => $this->imap->get_mailbox_name(), '_uid' => 
$uid), true)
                '_mbox' => $this->imap->get_mailbox_name(), '_uid' => 
$uid))
        );
