Hello,
We've had seg faults a couple of times a day on our servers, we upgraded to 1.2.17 and still have them.
running a coredump through dbg says:
Reading symbols from /usr/local/libexec/dovecot/imap-login...done. [New Thread 27962] Reading symbols from /lib64/ld-linux-x86-64.so.2...(no debugging symbols found)...done. Loaded symbols for /lib64/ld-linux-x86-64.so.2

We use NFS for mail store, and ramdisk for dovecot indexes. We do run the mail_log plugin.
Let me know if you need any more info though.
