index worker 2.3.7 undefined symbol errors (more info)

[Dirk Koopman]

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?
