Hello Timo,

Today I've moved one message from INBOX to a virtual folder which made imap processes crash as soon as INBOX was selected.

Jun 24 17:24:50 server dovecot: imap(user@example.com): Panic: file mail-index-view.c: line 149 (view_lookup_full): assertion failed: (seq > 0 && seq <= mail_index_view_get_messages_count(view))

Removing mail_log plugin made it working again. Even after re-enabling mail_log plugin there are no crashes anymore.

The full backtrace and doveconf -n output are attached.

Thanks for your help!
