Under certain cercumstances imap_sort() will cause an apache child process to seg 


      $mbox = imap_open('{}INBOX', 
                        'login', 'password', OP_READONLY);
      $results = imap_sort($mbox, 0, 0, SE_UID, 'UNSEEN');

Run against a mailbox with 1 UNSEEN message, produces the correct output:

    array(1) { [0]=> int(953) } 

However running against a mailbox without any UNSEEN messages, apache dies.  Attached 
is a gdb backtrace:

(gdb) run ./httpd -X -DSSL
Starting program: /usr/local/build/apache-build/apache-1.3.19/src/./httpd ./httpd -X 

Program received signal SIGSEGV, Segmentation fault.

This happens with both https and http as well as imaps and regular imap.
