When using newer version of Codestyling Localization the activated theme doesn't show up. Using an older version of the tool (eg. 1.99.16) will show the theme.
My theme has loaded the text domain with "load_theme_textdomain" in functions.php and is triggered by action "after_setup_theme". The theme has the same name as the textdomain.
I have tried with older versions of WP and getting the exact same result.
