On Drupal 6.x, the translation of the menu titles and descriptions (like given in the hook_menu() implementation) are already done by the core; there is no need to pass the translated text in the implementation of the hook, which would cause t() to be called twice.

cwgordon7 commentedYes, this was fixed with http://cvs.drupal.org/viewvc.py/drupal/contributions/modules/flexifilter... a while ago.

avpadernoThe issue has never been fixed in 6.x-1.1-rc1.
The development snapshot 6.x-1.x-dev is not even usable. Apart that, fixes done in a development snapshot should be back ported to the official release.

avpadernoI am closing this issue, which is for a not supported Drupal version.
