And inbox/test does not exist, results in:

Can you provide the core file using dovecot-sysreport tool?

https://raw.githubusercontent.com/dovecot/core/master/src/util/dovecot-sysre...

dovecot-sysreport --core /path/to/imap /path/to/core

Make sure you have gdb and dovecot-dbg installed for best results.
