I process my incoming e-mail via fetchmail->postfix->procmail->spamassassin.
Today I noticed that somehow incoming messages were being turned into empty
ones, and lines like
	[4081] warn: spamassassin: killed by SIGPIPE
appeared in my .procmail.log.

I believe that (for some reason) I suffered from spamassassin bug 6033
"kill_handler should exit with non-zero status"
https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6033
which seems to have been fixed upstream, as in the current lenny backport
version 3.3.1-1~bpo50+1.

I did eventually find my missing messages in /tmp/.spamassassinRANDOMSTUFFtmp,
but could such a bug fix be considered for any future lenny update?
