fts_solr: Lookup failed: 400 Bad Request / GET null null

the log file shows suspicious entries as follows:

Apr  3 09:14:49 xxx dovecot: imap(user at domain): Error: fts_solr:
Lookup failed: 400 Bad Request

The tomcat7 log shows for this request: - - [03/Apr/2016:09:14:49 +0200] "GET null null" 400 -

Dovecot is latest 2.2.23 with a pretty standard FTS config copied from the wiki:

mail_plugins = " acl fts fts_solr"
fts = solr
fts_solr = break-imap-search url=

Unfortunately I do not know (yet) which client action produces these
log lines. "GET null null" seems not to be a sensible request in any

Anyone seeing the same effect?
