doveadm backup panic, dsync-ibc.c, dsync_ibc_send_mailbox_tree_node, assertion failed: (*name != NULL)
Hi folks,
Not sure how much extra information I'll be able to provide on this, but
I'm experiencing a consistent, reproducible dsync backup error with a
single, specific account I'm trying to migrate from UW-IMAP / Panda (mix
mailbox) to a Dovecot 2.2.32 cluster. Didn't spot any core files laying
around.
Doveadm backup output, dovecot --version and dovecot -n below:
