dovecot - Jul 2018 - dsync panic

Hi,
I just upgraded from dovecot 2.2.19 to 2.3.2. "doveadm backup" worked
fine in v 2.2.19, but now panics (user with shared folder):
/opt/dovecot/bin/doveadm backup -u testuser -1 sdbox:/tmp/testuser

dsync(standl2): Panic: file mailbox-attribute.c: line 360
(mailbox_attribute_get_stream): assertion failed: (value_r->value != NULL ||
value_r->value_stream != NULL)
dsync(standl2): Error: Raw backtrace:

course)

Not sure why it panics, but at least your command line looks incorrect. 

please try: doveadm backup -u testuser sdbox:/tmp/testuser

your options are:

doveadm backup
doveadm sync
doveadm sync -1

I think I get pretty much the same issue:

with command:

doveadm backup -x "virtual/*" -x "shared/*" -u support
sdbox:/srv/dovecot/support/sdbox

with version 2.3.2.1
