[horde] ActiveSync does not include message body in sent folder

[Per Josefsson]

Dear all,

Messages saved in the sent folder has no body, am I alone with this 
problem?

There was a bug (11410) resulting in a patch aimed to address this 
problem. With version dcaefbcdebb051310d0a527db595a09feae5064d of 
Driver.php, the code snippet for saving has been moved one level up and 
the $headers object is forced into string. For me with those changes 
applied an entry is created in the sent folder though without any body 
(the actual message are missing).

Tracing the sending of a message I can see that in my case !$parrent is 
true, i.e., $copy is created from $raw_message->getMimeObject() at line 
1039.

Further, the headers->toString() (on line 1140) evaluates to (added a 
little code to dump the result of headers->toString()):

That is to my sent folder a message consisting of all headers followed 
by an empty line but with no message content is saved. The recipient 
however get a message with body.

About my setup
Ubuntu 12.04.11
Horde5 patch 5 + updated Driver.php + updated Adapter.php
iPad2

Does anyone else see this problem?
Can anyone figure what would solve my problem?

Best regards
