I'm using dovecot 2.2.24 on FreeBSD 10.3. I'm working on converting users from maildir to mdbox, for the usual reasons.

I have converted some test users and they generally work fine. But when I run "doveadm mailbox status" I get a Panic if I ask for the vsize field (or "all"), but other fields work fine. For example:

# doveadm mailbox status -u bubbacheex3 "messages" INBOX INBOX messages=53

# doveadm mailbox status -u bubbacheex3 "guid" INBOX INBOX guid=bf976912f3748957761d0100f906a3d0

# doveadm mailbox status -u bubbacheex3 "unseen" INBOX INBOX unseen=52

# doveadm mailbox status -u bubbacheex3 "vsize" INBOX doveadm(bubbacheex3): Panic: file file-lock.c: line 269: unreached Abort trap

I've only converted a few users, but they all exhibit this problem. I converted them with: dsync -u bubbacheex3 mirror maildir:/var/tmp/bubbacheex3

I have done a force-resync, which succeeds but doesn't change the behavior.

I spent a little time trying to get gdb running but didn't get very far (couldn't seem to get it to find the source files once I got a few levels deep in the call stack).

Before I beat my head on the gdb issue more, I thought I'd check here to see if anyone has any ideas. I didn't turn up anything in google or searching this list.

Here's my "doveconf -n" output:
