Comment 3 for bug 912695

OK, so this version of the patch to bluescan.c is fixed to handle error conditions gracefully { return(false) instead of exit(1) } and to report errors using syslog()

Another strange point that I don't understand -- pam_blue, as compiled from the source package, expects its configuration files in
  /etc/security/bluescan.conf
but the Ubuntu distribution expects
  /etc/security/bluesscan.conf [note the extra "s"]
