Search Builder fails in an internationalised environment

In an international environment, i.e. one whose base language is not en_US, the title and description columns in tables are in the form  title_ll_CC, where ll is the language and CC is the country.  So, for example civicrm_option_group has the following relevant columns in the en_GB environment.

title_en_GB
description_en_GB

/administrator/components/com_civicrm/civicrm/CRM/Core/BAO/OptionGroup.php(197): CRM_Core_BAO_OptionGroup::getTitlesByNames() is, I think, returning name and title, not name and title_en_GB, so the subsequent query fails with unknown column.

I intend to investigate further, but this is just to flag the issue.
