I only have this problem if the message is both: encrypted and signed. I
think that is due to the fact, that those messages are first smime signed and
then smime encrypted. When receiving those messages mutt can decrypt the
first layer resulting in a signed message, i.e. one with only the smime.p7m
attachment.
Mutt's pager seems to be able to detect that a message is indeed signed and
then calls the smime_verify command, which the attachment viewing function
does not.
I don't know wether it is possible to work around that ...
As I get those very rarely I decrypt and verify such a message outside of
mutt and then merge in the result (with some deletion of Content-... headers)
via mutt's "edit message" command.
Best regards
