3.2.3 and qemu: could not init smb messaging context

Binary package hint: samba

I've got win2k in a qemu vm and I'm using '-smb' with my home directory. When I try to reach that network drive, smbd crashes. The log is below. And w2k reports that the network path was not found.
Smbd reports that it is dumping core in /var/log/samba/cores/smbd, but nothing shows up there.

So there might be two bugs here, one being that it crashes, as in the log below.
The second being that there is no coredump.

Note that I 'chgrp adm /var/*/samba' and 'chmod g+rw /var/*/samba' to be able to run samba as a regular user. This is because of bug 50385.

This is intrepid, uptodate to today, 5-oct-2008, it is 2:3.2.3-1ubuntu2. And this is a x86_64 install.
If there's something else you'd like me to do, just ask. It is very easy to reproduce.

This is all that is logged for the whole run in /var/log/samba/smbd.log:
