Function mm-view-pkcs7-verify calls (mm-insert-part handle), which
somehow deals with the text for subsequent display.  The search for
"Content-Type" suggests that this is only meant for multi-part
e-mails, for which it really works.  In this case, however, it
inserts the text among binary data, which seems to fail subsequently.

Best wishes
