dovecot - Apr 2010 - dsync panic in dsync-worker-local.c - 2.0.beta4

Hello,

While testing mailbox conversion I encountered a Panic in dsync on a few users
mailboxes.

Running dovecot 2.0.beta4 on RedHat Enterprise Linux 5 (x86_64).

I tried to compile the code with -ggdb and debug some more before posting this,
but I was unsuccessful. Running dsync from a source tree is hard because of all
the dependencies on shares libraries. Is it possbile to build static binaries?

Panic message and backtrace included below (anonymized):
dsync(user): Error:

Can you still reproduce this with nightly snapshot?
