[horde] Warning message from Magic.php when attaching a file in IMP compose window

[Robin John West]

We have a working Horde 3.2.1/IMP 4.2 installation on a RH Linux  
server (PHP 4.3.2), and I'm working on setting up the same on a  
Solaris 10 machine (PHP 5.2.6).

On the Solaris installation I'm getting a warning message at the top  
of the page whenever I try to attach a file to a message in the IMP  
compose page. The message is preceded by several lines of what looks  
like mangled serialized data:

n__________E";s:16:"applicati?-ar";s:19:"!n________64E";s:16?plication/data";s:19?/local/bin/a?:11:?t/sc?";}i:18;a:3:{s:18:"FiLeStArTfIlEsTaR?:20:?t/x-apple-binsci?:18:"#! ?/loc?csh";s:17:"applicati?-csh";s:18:"%!PS-AdobeFont-1.0";s:10:"fo?ype1";}i:17;a:1:{s:17:"#?r/local/tcsh";s:17:"appl?ion/??i:16;a:1?:16:?ended Module?:15:"aud?-ft2-mod";s:16:"???";s:17:"?????:16:"#! ?/bin??:17:?lication/x-awk";s:16:"#!?r/bin/nawk";s:17?plication/x-awk";s:16:"#?sr/b?erl";s:18:"applicati???:16:"#!  
?/bin??:17:?lication/x-awk";s:16:"#!?r/bin/nawk";s:17?plication/x-awk";s:16:"#?sr/b?erl";s:18:"applicati???:16:"ndebian";s:18:"applicati?-dpk?:14:"#!/usr/bin/awk";s:17:"applicati?-awk";s:14:"
Warning: Variable passed to each() is not an array or object in  
/opt/luminis/dalhousie/horde/lib/Horde/MIME/Magic.php on line 200

After the message the compose page is redisplayed with the file  
successfully attached.

Everything works fine with no warnings on the Linux installation. I  
have checked horde/lib/Horde/MIME/mime.magic.php to make sure it isn't  
corrupted - it is identical on both servers. I also tried this test  
script on both servers:

<?php  require_once('mime.magic.php');
  while (list($i, $j) = each($mime_magic)) {
    printf("%s, %s\n", $i, $j);
  }

Works fine on the linux box, produces the warning message on the  
Solaris box. So the only difference is the OS and the PHP version.  
Anyone have an idea what the problem might be?

Thanks in advance.
