Segfault with snort 2.0

I was trying to activate conversation/portscan2 but end up getting a blatant segfault:

rpc_decode arguments:
    Ports to decode RPC on: 111 32771
    alert_fragments: INACTIVE
    alert_large_fragments: ACTIVE
    alert_incomplete: ACTIVE
    alert_multiple_requests: ACTIVE
telnet_decode arguments:
    Ports to decode telnet on: 21 23 25 119
Using LOCAL time
Segmentation fault

The relevant part of /etc/snort/snort.config that "screws up" is shown below (lines prefixed with ~ make it fault if active, or if commented out let it run just fine):

~preprocessor conversation: allowed_ip_protocols 1 6 17, timeout 60, max_conversations 3000

~preprocessor portscan2: scanners_max 256, targets_max 1024, target_limit 5, port_limit 20, timeout 60

Granted it's probably something silly, I haven't enabled these preprocessors before. This is using:
