Report won't run, reports NULL

I have tried running the report (not skipping anything) It initializes and then shows how many checks it will be doing in the progress bar. that immediatly goes away and says %NULL. I choose to skip all but one check. (same issue)
Error log reports:

$task_message = '';
if ((list($function, $args) = reset($current_set['operations'])) && function_exists($function)) {
// Build the 'context' array, execute the function call,
// and retrieve the user message.
$batch_context = array('sandbox' => &$current_set['sandbox'], 'results' => &$current_set['results'], 'finished' => &$finished, 'message' => &$task_message);
// Process the current operation.
call_user_func_array($function, array_merge($args, array(&$batch_context)));
}

if ($finished >= 1) {
// Make sure this step isn't counted double when computing $current.
$finished = 0;
// Remove the operation and clear the sandbox.
array_shift($current_set['operations']);
$current_set['sandbox'] = array();
}

Any Ideas?
once it locks up like this, if I hit the back arrow, I see this on screen:
An HTTP error 0 occurred. /batch?id=330&op=do
