I put a Lure II vanilla rod in an autofisher (1.2.3b), baiting it with ants. I let it work a few seconds and it killed my server. I don't even have time to start it, login and remove the rod before it crashes again.
Here is the begining of the crash report:

Either disable vanilla rods catching vanilla loot, don't use vanilla rods in an autofisher or grab this development version : http://ci.tterrag.com/job/Mariculture/138/
