Hello List!
I've encountered an error after upgrading my system and dovecot. I guess it's probably a result of a configuration problem, however after quite some tinkering with configuration I am still missing the source of the problem.
Sep 28 16:57:21 shwurzbung dovecot: imap(wizz): Panic: file mail-storage.c: line 834 (mailbox_verify_name): assertion failed: (strncmp(vname, ns->prefix, ns->prefix_len-1) == 0) Sep 28 16:57:21 shwurzbung dovecot: imap(wizz): Fatal: master: service(imap): child 23203 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes })
The problem above appears with both dovecot 2.2.5 and 2.2.6. It did not happen while using dovecot 2.1.12. Operating system is OpenBSD 5.4-current and AMD64. FS type is FFS (default for OpenBSD).
Output of dovecot -n:
# 2.2.6: /etc/dovecot/dovecot.conf

Thanks in advance for any pointers to a resolution.
