[dev] imp - large INBOX

[Rick Romero]

A couple times I've seen odd issue with IMP and DIMP Accessing my  
INBOX (>650 msgs), and I would get 'Error when communicating with the  
server' or 'Unable to generate message list' - and I see an empty INBOX.

In my lighttpd logs I see:
2011-03-14 09:52:03: (mod_fastcgi.c.2701) FastCGI-stderr: PHP Fatal  
error:  Call to a member function getEnvelope() on a non-object in  
/usr/local/www/data/horde_git/horde/framework/Imap_Client/lib/Horde/Imap/Client/Socket.php on line  
1947

So I threw an if is_object() before that line, and enclosed the rest  
in braces, and it appears to work now.   In IMP, I get a message list  
and can move around normally - though it's not sorted.  In DIMP,  
everything seems to be working correctly.

                     foreach ($slice as $num) {
                       if ( is_object($fetch_res[$num]) ){
                         $env = $fetch_res[$num]->getEnvelope();
                         if (empty($env->$field)) {
                             $sorted[$num] = null;
                         } else {
                             $tmp = ($display_sort &&  
!empty($env->$field[0]['personal']))
                                 ? 'personal'
                                 : 'mailbox';
                             $sorted[$num] = $env->$field[0][$tmp];
                         }
                       }
                     }
