Getting an error while migrating a site on Aegir

While migrating a site on Aegir, I am facing a weird issue related location module.
Here is what I am getting:-

Drush command terminated abnormally due to an unrecoverable error. Error: Call to a member function override_option() on a non-object in /var/aegir/platforms/u/sites/all/modules/contrib/location/location.views_default.inc, line 22

Any idea about this?
