Michael,
I have the same problem. After a little debugging, I found that
pcapheader->caplen is always equal to [(datlen*2) + pkt_head_sz] but in
your "if" statement (in sbk_extract.c) you check to see if
pcapheader->caplen = datlen + pkt_head_sz. That will fail. So, it
will complain about the malformed package.
After putting that in, it seems to work fine. But I haven't fully
tested to see if all functions work.
I'm running sebekd-3.0.3 on Fedora 4. I hope that and pcap output from
Rich Compton will help you looking into it.

honeywall
Can you run tcpdump on roo and send me the pcap output? I cannot
reproduce this in my testing here. Also, what version of roo? Is it
1.0hw189?
Thanks,
