v2.3.1: Event leaked (parent=(nil)): http-client.c:137 and 439

1 May 2018

      Hi,
After upgrade to dovecot 2.3.1, many IMAP clients cause errors in
dovecot log:
May 01 20:15:51 tiger dovecot[21985]: imap: Warning: Event
0x555fd3c01630 leaked (parent=(nil)): http-client.c:137
May 01 20:15:51 tiger dovecot[21985]: imap: Warning: Event
0x555fd3c00140 leaked (parent=(nil)): http-client.c:439
Namely:

roundcube 1.3.3
offlineimap
nextcloud mail app

Despite the errors, the basic functionality seems to work - mails are
received by the client. However, the GUI clients display an "internal
server error" message window on each refresh.
Some other clients do not create any issues:

MailDroid (Android)
getmail

Anybody got a similar behaviour?
