[kronolith] Free/Busy Retrieve Error

[akulick@backup.corp.eoscene.com]

There appears to be an error in Free/Busy check in which the URL is
determined correctly, but the data retrieval is failing.  Specifically,
placing an "echo $url;" spits out the correct URL.  Retrieval via http
works correctly.  However, the function returns nothing, echo $data
returns no meaningful data and fails if ($data).

I am unfortunately not smart enough to understand where
@file_get_contents calls too, but it would appear it is not operating
correctly.

Any help would be appreciated, even a pointer to the file_get_data function and I could try to get to the bottom of it and produce a diff/patch.

kronolith/lib/Kronolith.php line 850:

        // Check if we can retrieve a VFB from the Free/Busy URL, if
        // one is set.
        $url = Kronolith::getFreeBusyUrl($email);
        if (is_a($url, 'PEAR_Error')) {
            return $url;
        }
        if (!empty($url)) {
            $data = @file_get_contents($url);
            if ($data) {
                $vCal = &new Horde_iCalendar();
                $vCal->parsevCalendar($data);

                $vFb = &$vCal->findComponent('VFREEBUSY');
                if ($vFb !== false) {
                    return $vFb;
                }
            }
        }
