NULL context in mlfi_close

[Gregory Szeszko]

I get the following error message when running spamassassin and
spamass-milter:

Apr 22 01:50:26 iserve2 spamass-milter[13103]: NULL context in
mlfi_close! Should not happen!
Apr 22 01:50:26 iserve2 spamass-milter[13103]: Could not extract score
from <>

My sendmail.mc contains these lines:

INPUT_MAIL_FILTER(`clamav',`S=local:/var/run/clamav/clamav-milter.sock,
F=, T=S:4m;R:4m')dnl
INPUT_MAIL_FILTER(`spamassassin',`S=local:/var/run/spammilter/spamass.sock,
F=, T=C:30m;S:30m;R:30m;E:30m')dnl
define(`confINPUT_MAIL_FILTERS', `clamav,spamassassin')dnl

I initially thought that it might be caused by muliptle
INPUT_MAIL_FILTERS in sendmail.mc.  But I still get this error even if
spamassassin is the only milter, like this:

dnl
INPUT_MAIL_FILTER(`clamav',`S=local:/var/run/clamav/clamav-milter.sock,
F=, T=S:4m;R:4m')dnl
INPUT_MAIL_FILTER(`spamassassin',`S=local:/var/run/spammilter/spamass.sock,
F=, T=C:30m;S:30m;R:30m;E:30m')dnl
dnl define(`confINPUT_MAIL_FILTERS', `clamav,spamassassin')dnl

Any ideas?
