"Oops!" while working with translations in Launchpad

When I looked at this page https://launchpad.net/distros/ubuntu/dapper/+source/lftp/+pots/lftp/ru/+translate?show=need_review and tried to disable "Someone should review this translation" chebox for item number 158 I got the page with URL https://launchpad.net/distros/ubuntu/dapper/+source/lftp/+pots/lftp/ru/+translate
saying "Oops! Sorry, something just went wrong in Launchpad. We’ve recorded what happened, and we’ll fix it as soon as possible. Apologies for the inconvenience. ..."

Error ID is OOPS-76B333
