I can confirm the problem but your explanation doesn't make sense. You seem to
not have understood how crypto works. See:


You need verify the certificate in order to be sure that you encrypt to the
right key. Encrypting to the MitM key is not part of the concept
"confidentiality". Signing keys makes them valid. You need valid keys both for
serious encryption and for serious signature checking.

Nonetheless this must be fixed because the user must be free to decide to use
the key anyway and it is really evil to force the user to certify the key first
(or even worse: set it to ultimate trust).
