[imp] Search "entire message" member function fetch() on a non-object

Sat Jun 7 14:18:33 UTC 2014

Hi,

at the moment I use IMP-6.2.0beta1* with Horde-5.2.0beta2 and  
Horde_Core-2.12.0beta2 since there are some bugs which affect me in  
IMP-6.2.0beta2.

One of my user can search in the INBOX with "entire message", get the  
search result and can open the message in the preview mode.
Same user can search in the "Sent" folder with "entire message", get  
the search result but after select a message or double click on it  
Horde show "Error when communicating with the server.".

Horde.log:
2014-06-07T13:53:02+00:00 EMERG: HORDE [imp] Call to a member function  
fetch() on a non-object [pid 17325 on line 1616 of  
"/var/www/http/horde/imp/lib/Contents.php"]

POST https://example.com/horde/services/ajax.php/imp/showMessage  
[HTTP/1.0 500 Internal Server Error 297ms]
"onFailure" {request: Object, transport: XMLHttpRequest, readyState:  
4, status: 500, statusText: "Internal Server Error", responseText:  
"<html>
<head><title>Horde :: Fatal Error</title></head>
<body style="background:#fff; color:#000"><h1>A fatal error has  
occurred</h1><h3>Call to a member function fetch() on a  
non-object</h3><h3>Details have been logged for the  
administrator.</h3></body></html>", headerJSON: null, responseXML:  
null, responseJSON: null}

It works sometimes in sent, but do not found the logic when it works  
an when not. :(

Any ideas?
* It doesn't works with imp-6.2.0dev201406061803.tgz
