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

[Milan Knížek]

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?
