I've recently reinstalled horde for an FC8 upgrade and choose to download
from the cvs as per my fc6 install.  However when I got framework from the
horde cvs there appears to have been a change to how the Block code has
been written specifically the View.php and perhaps others.  The result is
that on logging into my horde account I can NOT see any block and I
record:

 PHP Warning:  Invalid argument supplied for foreach() in
/usr/share/pear/Horde/Block/Layout/View.php

This is with version  * $Horde: framework/Block/Block/Layout/View.php,v
1.4.2.9 2008/01/02 11:30:23 jan Exp $

If I copy my old fc6 /usr/share/pear/Horde directory to my FC8 install all
works again? Comparing the code there appears to be significant changes
between the two versions of Block/Layout/View.php

FC6 version:  * $Horde: framework/Block/Block/Layout/View.php,v 1.16

Could it be based around this being missing in the latest version?
function Horde_Block_Layout_View($layout = '')
    {
        $this->_layout = @unserialize($layout);
        if (!$this->_layout) {
            $this->_layout = array();
        }
    }
