can mutt handle self-signed SSL certs? smime_keys blocks it

I've used the following procedure to attempt to create a simple key
for use with S/MIME - without involving a CA:

$ smime_keys init
$ touch ~/.smime/ca-bundle.crt
$ openssl genrsa -out my.key 2048
$ openssl req -new -key my.key -out my_request.csr
$ openssl x509 -req -days 3650 -in my_request.csr -signkey my.key -out my.crt
$ openssl pkcs12 -keypbe PBE-SHA1-3DES\
-certpbe PBE-SHA1-3DES\
-export\
-in my.crt\
-inkey my.key\
-out my_pkcs12.pfx\
-name "Me"
$ smime_keys add_p12 my_pkcs12.pfx

Verifying - Enter PEM pass phrase:
Couldn't identify root certificate!
No root and no intermediate certificates. Can't continue. at /usr/bin/smime_keys line 708.

Mutt seems to be dependant on some unforgiving perl code, which
expects all keys to be signed by a CA.. or so it seems.
