Some supplemental information:
This is happening on every email delivered into Dovecot via LMTP. The curious things are that the message is a) successfully delivered and b) sieved into the correct directory.
Another observation is that:
mail_deliver_ctx_get_log_var_expand_table
is defined globally in core/src/lib-lda/mail-deliver.c (and used there) but the ONLY external call in the entire dovecot tree is from pigeonhole/src/plugins/lda-sieve/lda-sieve-log.c.
I am not using lda but it seems to be part of core. So, as I am only using lmtp, why is pigeonhole using lda-sieve at all?
Can I work around the error message by some config magic (as I did by calling the correct plugin for imap_sieve) or is this an actual bug? Could this be fixed simply by including mail-deliver.h in lda-sieve-log.c?

(I think I fixed this one by a config change)
But I am left with this:
