[chora] Browsing Error

[Hammad]

Hi Guys-

RedHat 9.0, PHP 4.2.2-17
I am currently trying to get the latest version of horde (3.0,
horde-2003-06-18.tar.gz) and chora (2.0, chora-2003-06-18.tar.gz)
configured and am getting the following "NOTICE" when I click on some archive.
Any help will be appreciated.

Notice: Undefined index: default in
/var/www/html/horde-2003-06-18/lib/MIME/Viewer.php on line 380
