To translate "Custom Meta Widget" I used the plugin "Codestyling Localization".
With version 1.3.5_a no problems 24 strings of characters are proposed to be translated.
With version 1.4.0 only 14 strings are proposed to be translated.
Several strings of characters are no longer proposed to be translated, for example:
Show "Register/Admin" link?
Show "Log in/out" link?
Show "Entries RSS" link?
Show "Comments RSS" link?
Show "WordPress.org" link?
Show the custom link?
