[horde] Linked attachments don't work as expected

I am recently update my horde installation to horde 5.2.4/imp 6.2.7  
and have an issue when try to send linked attachments.

My imp configuration is:

$conf['compose']['use_vfs'] = true;
$conf['compose']['link_attachments_notify'] = false;
$conf['compose']['link_attach_threshold'] = 5242880;
$conf['compose']['link_attach_size_hard'] = 5242880;
$conf['compose']['link_attach_size_limit'] = 104857600;
$conf['compose']['link_attachments'] = true;
$conf['compose']['attach_size_limit'] = 0;
$conf['compose']['attach_count_limit'] = 0;

When I try to send a single attached file bigger than 5 MB, it works  
as expected.
When I try to send, say 3 files of 2 MB each, the response is "Error  
when communicating with the server" and the mail is not sent.

In my log I see the following message:

2015-02-27T11:17:06+01:00 EMERG: HORDE [imp] Call to a member function  
setRaw() on a non-object [pid 29524 on line 2909 of  
2015-02-27T11:17:06+01:00 DEBUG: HORDE 1.  

I saw there is a bug solution in bugs.horde.org (ticket 13665), but  
this does not fix my issue.

Thank you in advantage for any solution that fixes this issue.
Best regards.
