Yes, except for text plain messages, when the other kinds of message are to be signed and encrypted, just before the encryption password is asked for, a yellow box appears saying that the signature failed because of wrong password.
There is something wrong or not handled in the signature process. And of course, signature verification fails. I also tried various combinations manually with gpg on those messages to verify the signature and they all failed.

Thanks for the samples. I see now what's missing. I also see that the
second example has wrong structure (the attachment is not signed), which
means signed messages creation would need a fix too. I'll work on these
to be fixed before 1.2-stable release.
