Trust in link titles breaks router table

I was brought in to a project at work that had been underway for a few months. They were happily styling the drupal commerce and other components and wanted me to build the admin dashboard. I was unable to go to the new panel pages I was making because drush cc menu was clogged with an error:
WD menu: PDOException: SQLSTATE[23000]: Integrity constraint violation ... title cannot be NULL

after some googling and then reading through the trememdously long error message, I found this record:

That is one complete entry to the database, I counted.
You will notice that placeholder 128, which should be holding what goes in to t() for the title, is empty. Also, holder 120 references this module.
With a quick grep and the prior googling, I found that rules_linkevent.module has the same trusting idea that also hurt http://drupal.org/node/619542 and http://drupal.org/node/1320634
