I get the error above for some reason when I try to manually execute the /cron.php file.

Here is my config.xml for a module that I think is causing the issue

```
<?xml version="1.0" encoding="UTF-8"?>

<!-- The root node for Magento module configuration -->
<config>

    <!--
        The module's node contains basic
        information about each Magento module
    -->
    <modules>

        <!--
            This must exactly match the namespace and module's folder
            names, with directory separators replaced by underscores
        -->
        <Company_ScheduledPriceDrop>

            <!-- The version of our module, starting at 0.0.1 -->
            <version>0.0.1</version>

        </Company_ScheduledPriceDrop>

    </modules>

    <crontab>
        <jobs>
            <Company_ScheduledPriceDrop>
                <schedule>
                    <cron_expr>*/5 * * * *</cron_expr>
                </schedule>
                <run>
                    <model>Company_ScheduledPriceDrop/observer::setPrice</model>
                </run>
            </Company_ScheduledPriceDrop>
        </jobs>
    </crontab>

</config>

```

And here is the observer file that is being called

```
<?php

class Company_ScheduledPriceDrop_Model_Observer extends Mage_Core_Model_Abstract
{
   public function setPrice()
   { 
        Mage::log("WORKS!");
   }
}

```

I'm not sure what the error means, can anyone help please?
