This has been fixed at 2013-05-01 (bug#14304), so it will work
properly in the forthcoming Emacs 24.4.  Here's a patch for 24.3:

Hi there,

the calls to gnus-completing-read in smime-sign-buffer and
smime-decrypt-buffer do not provide completion support.

If I change gnus-completing-read-function from
gnus-emacs-completing-read to completing-read, everything works:

(setq gnus-completing-read-function 'completing-read)

A related problem is reported there:

Best wishes
