FYI, I initially found this bug when parse the packets:
pkt = packet.Packet(data)
for p in pkt.protocols:
print p
something_else()
if remove __str__() entirely, would the print work correctly?

Changed pack string of IPv6 address from former '!4I' to '!16s'.
Might need an IPv6Addr class or something to convert between human readable
address and binary representation.

Hello Isaku,
A capture file is attached to the mail.
The IP 10.0.2.15 is a virtual machine running mininet, and IP 10.109.242.118
is the host running ryu.
I suspect that it's the first packetIn packets cause ryu to crash as you
can see the FIN packets are only a few milliseconds after
ckets that ryu cannot handle properly, and then ryu crashes.
Maybe this is a bug of ryu?
FYI, I'm using ryu with mininet(open vSwitch 1.9.0)
