When opening mails in IMP via POP3 everytime a mail is opened a red  
box appears telling "Communication error with server" and the  
following error messages appear in error log instead of showing the  
mail:

PHP Fatal error:  __clone method called on non-object in  
/usr/share/php/Horde/Imap/Client/Data/Envelope.php on line 90
PHP Fatal error:  spl_autoload(): Class Horde_Db_Value_Binary could  
not be loaded in /usr/share/php/Horde/SessionHandler/Storage/Sql.php  
on line 130

I tracked this error back:

When opening an IMAP mailbox all mail headers are returned by the IMAP  
classes as an instance of "Horde_Mail_Rfc822_Address", when opening  
the same mailbox with POP3 headers are returned as a simple Array  
(which has no clone method and therefore fails with the error message  
above).
