What steps will reproduce the problem?
1. Enable the ZFDebug
2. It is shown several warnings and notices regarding the plugin Cache.php

That show me the error of my application/Error of the ZFDebug

Please provide any additional information below.
I suggest to add a simple verification in the plugin Cache.php in
getPanel() method if is empty or not:

    public function getPanel()
    {
        $panel = '';

        # Support for APC
        if (function_exists('apc_sma_info') && ini_get('apc.enabled')) {
            $mem = apc_sma_info();
            // Verify if $mem is not empty
            if (!empty($mem)) {
            $mem_size = $mem['num_seg']*$mem['seg_size'];
                $mem_avail = $mem['avail_mem'];
            $mem_used = $mem_size-$mem_avail;

            $cache = apc_cache_info();

            $panel .= '<h4>APC '.phpversion('apc').' Enabled</h4>';
            $panel .= round($mem_avail/1024/1024, 1).'M
available,'.round($mem_used/1024/1024, 1).'M used<br />'
                        . $cache['num_entries'].' Files cached
('.round($cache['mem_size']/1024/1024, 1).'M)<br />'
                        . $cache['num_hits'].' Hits
('.round($cache['num_hits'] * 100 /
($cache['num_hits']+$cache['num_misses']), 1).'%)<br />'
                        . $cache['expunges'].' Expunges (cache full count)';
            }
        }
    ...
