Drupal 7 - Error Reported in log - array_splice() expects parameter in template.php

In Report Logs we we’re getting these errors on Clearing the Cache.  

Warning: array_splice() expects parameter 1 to be array, null given in omega_theme_registry_alter() (line 458 of */sites/all/themes/contrib/omega/omega/template.php).

Warning: array_search() expects parameter 2 to be array, null given in omega_theme_registry_alter() (line 445 of /Users/DJ/Sites/mampsites/sccbb/sites/all/themes/contrib/omega/omega/template.php).

Warning: array_unshift() expects parameter 1 to be array, null given in omega_theme_registry_alter() (line 447 of /Users/DJ/Sites/mampsites/sccbb/sites/all/themes/contrib/omega/omega/template.php).

Warning: array_splice() expects parameter 1 to be array, null given in omega_theme_registry_alter() (line 449 of /Users/DJ/Sites/mampsites/sccbb/sites/all/themes/contrib/omega/omega/template.php).

Notice: Undefined index: preprocess functions in omega_theme_registry_alter() (line 445 of /Users/DJ/Sites/mampsites/sccbb/sites/all/themes/contrib/omega/omega/template.php).

To test this I locally ran this test in the omega/template.php at line 445

// @todo temporary debugging code to look for an error
// check to see if this is an arry
if (!is_array($registry[$hook]['preprocess functions'])){
  watchdog('!array preprocess func', $hook);
}
if (!isset($registry[$hook]['preprocess functions'])){
  watchdog('!isset preprocess func', $hook);
}
// @todo end debugging

This report any hook preprocess functions that are not as should be .   Which returned the one result .  

‘block_swiper’

On checking we have a Swiper module installed. When disabled we no longer receive a PHP error message.   Also note on checking Clear Cache needs to be run each time.
