Hello Martin,

1) There is warning in the config regarding using stack traces and how
it can reveal secure information.
2) This particular problem has been solved in RT 3.8.8 RC2.

> This causes error shown in attached page, revealing password to

> I am providing a quick patch that catches the exception generated by
