dovecot - Aug 2005 - IMAP can't read inbox: istream_raw_mbox_get_body_size assertion failed

Yesterday, I upgraded my debian packages from 0.99.14 to 0.99.20050712-2. IMAP
service has not been reliable since, and I was seeing crashes with one user.

I tried deleting the user's .subscriptions and .imap folders, and forcing
the client (Mac OS X's Mail.app) to redownload everything, but that resulted
in an empty inbox.

Here's what I have:

# dpkg -l dovecot*

Here's what's in mail.log:

I got a core dump. Here it is:

#13 0x0809b65b in io_loop_run ()
#14 0x080602aa in main ()

I downgraded to 0.99.14 and put in the old configuration file and it seems to be
working now.

What's going on?

Already replied into Debian bug report, here's to everyone:

This problem most likely is caused by CR characters in linefeeds in the
mbox file. 1.0-stable releases don't handle that, latest 1.0-test does..
I'll try to put out 1.0alpha release out soon, maybe Debian will start
using that too :)

On friday I downgraded dovecot to stable 0.99.14-1, because the testing 
package just didn't work. See the message I sent to this list on thurday of 
last week.
