When i add this require_once in _buildPartData() it does'nt work, i 
tried to add it in buildAttachment() and in buildAllAttachments() 
where _buildPartData() is called but it does'nt work to. the only 
place i found is at the top of file.

Guess it wouldn't really hurt to add a require_once in 
_buildPartData() to ensure this error message never occurs - although 
I still can not reproduce this.

When i add the following line at the begining of 
horde/imp/lib/Compose.php it works fine:



require_once IMP_BASE . '/lib/MIME/Contents.php';



What do you think of that modification?



I joined the patch.

OK, i saw the problem when i submited the comment : i am using PHP5...

But this is the only bug i found (due to PHP5) with Horde on apache2/PHP5.

I don't understand why i have this problem when i forward the entire 
message or when i forward only the attachments and not when i forward 
message text only ?...



Fabrice

Yes i'm using the latest snapshot of HEAD Horde Framework and 
conponents. Horde is running on the following system :



OS : CentOS 4



Http server : httpd-2.0.52-28.ent.centos4



PHP  :

php-pdo-5.1.6-1oci8

php-devel-5.1.6-1oci8

php-eaccelerator-5.1.6_0.9.5rc1-1

php-5.1.6-1oci8

php-pgsql-5.1.6-1oci8

php-gd-5.1.6-1oci8

php-xml-5.1.6-1oci8

php-mysql-5.1.6-1oci8

php-pear-1.4.6-2

php-imap-5.1.6-1oci8

php-ldap-5.1.6-1oci8



Thank you for your help

I can't reproduce this.  Are you sure you are using most recent HEAD 
of imp/dimp/horde?

When i forward entire message or attachments only, using Dimp (HEAD 
version) i have the following PHP error:



[error] [client 10.10.206.41] PHP Fatal error:   
IMP_Compose::_buildPartData() [<a 
href='function.IMP-Compose--buildPartData'>function.IMP-Compose--buildPartData</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition &quot;MIME_Part&quot; of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition  in /var/www/html/horde/imp/lib/Compose.php on line 1986, referer:

Can you help me ???
