[Dovecot] assertion failed in mail-index.c

Hi,

I have this: Jan 04 15:55:21 pop3(jfm47): Panic: file mail-index.c: line 257 (mail_index_keyword_lookup_or_create): assertion failed: (*keyword != '\0') Jan 04 15:55:21 master: Error: service(pop3): child 3391 killed with signal 6 (core not dumped - set service pop3 { drop_priv_before_exec=yes }) I don't know why this happened, but wouldn't be the "self healing" (seen in the wiki I think :) kick in here? I mean it's even better to completely remove the index than dying and make the mailbox inaccessible.

Thanks,
