I created a backport of samba 3.0.22-1, which is available from here:
http://people.backports.org/~tretkowski/upload/samba/
The packages are currently still uploading, we have a slow internet
connection here at DebConf6. That's also the reason why I'm not going
to upload the 180 MB big samba-dbg package now. :)
