Comment # 4 on bug 10129 from 
I haven't tried any of the other builds. 

The problem appears when I add SAs with parameters like

Protocol: IPV4
SPI: 0x6789abcd

Encryption: AES-CBC(RFC3602)
Encryption Key:
0x6789abcd6789abcd6789abcd6789abcd6789abcd6789abcd6789abcd6789abcd

Authentication: HMAC-SHA1 (RFC2404)
Authentication Key: 0x6789abcd6789abcd6789abcd6789abcd
