[Dovecot] In 1.1.beta3, COPY cmd results in msg with Content-length: 0 and no text

[Eric Weaver]

I run Thunderbird with message filters that sort mail into other 
folders, and this has killed me for the day.

COPY commands (and I have verified this with a manual test) result in 
the message headers coming out correct but the body totally missing.

Is this a known issue being addressed?

Thanks
