[Bugfix] Mutt 1.4.1i crashes with certain keyrings



Hi,

I use Mutt 1.4.1i. If I try to send an encrypted mail to someone and
the key isn't automagically found, mutt shows a sorted list of the
keys in my public keyring. Unfortunately, on Solaris 8 my public
keyring manages to crash mutt with a SIGSEGV. I've this with the
attached patch. However, I couldn't comprehend where things go
really wrong and the NULL pointer is inserted. So maybe this is
just a workaround.
