Error: fts_solr: received invalid uid

Hi John,

You are right this was not a dovecot solr query. It is really strange 
everything seems to work with Dovecot 2.3.4. E.g. search and  rebuilding 
index from scratch using doveadm. As soon as I use version  2.3.13 
things are getting wild: dovecot crashed when I re-scan the index using 
doveadm and search does not work anymore, after re-scan:

Panic: file http-client-request.c: line 1240 
(http_client_request_send_more): assertion failed: (req->payload_input 
!= NULL)

and solr:

Seems like dovecot is sending an empty query?
