[Dovecot] dovecot-1.2.12 core

[Thomas Hummel]

Hi Timo,

just to report that

  . dovecot-1.2.12 which ran fine for several month
  . on FreeBSD 7.2-STABLE (/usr/obj/usr/src/sys/GENERIC  amd64)
  . using Maildir (mailboxes, control and indexes on NFS)

has crashed this morning on our server.

I found nothing special in the logfile.

Attached are dovecot -n output and a gdb backtrace of the core file.

Thanks
