[imp] pdf mime type

[G G Papazoglou]

Hi to all.

I've been experimenting trying to enable pdf viewing support in imp, using
pdftohtml 0.34. So I have added the respective entry in
config/mime_drivers.php:

$mime_drivers_map['horde']['registered'] = array(
    'php', 'tgz', 'vcard', 'enriched', 'msword', 'msexcel','pdf'

$mime_drivers['horde']['pdf']['location'] = '/usr/local/bin/pdftohtml';
$mime_drivers['horde']['pdf']['inline'] = true;
$mime_drivers['horde']['pdf']['handles'] = array(
    'application/pdf',
    'x-extension/pdf');
$mime_drivers['horde']['pdf']['icons'] = array(
    'default' => 'pdf.gif');

and of course pdftohtml works properly. However when trying from inside imp,
I get a window with the following error:

Fatal error: Call to a member function on a non-object in
/usr/local/apache/htdocs/horde/imp/view.php on line 77

Any ideas please?

Regards,
Greg
