MailScanner-4.68.8 hangs at startup

Hi all. I am attempting to upgrade from a previous MailSCanner-4.58.8
installation; however, I am running into a rather interesting problem. If I
specify Run as User, and Run as Group to be postfix in MailScanner.conf, and
then try to start MailSCanner with check_mailscanner, the parent hangs without
starting any children. I was able to narrow down this precise cause by taking an
original MailScanner.conf, and only editing the two above options, and
specifying MTA to be Postfix. If I don't specify Run as USer or Run as Group to
be Postfix, MailSCanner starts up just fine. I was also able to strace the
parent, which seems to show the children attempting to start and then exiting:
fork() = 32467
rt_sigprocmask(SIG_SETMASK, [CHLD], NULL, 8) = 0
close(4) = 0
close(4) = -1 EBADF (Bad file descriptor)

Anyone have any other ideas that I could try to get this going? The only thing I
modified from the previous 4.58.8 installation was a new version of
SpamAssassin, and of course the newer configuration file. I am also running
Postfix-2.3.7. Thanks in advance!
