runtime error: slice bounds out of range

[GoogleCodeExporter]

Hello! It's me again :)

I compiled (big win!) and run this code: 
https://gist.github.com/pavel-odintsov/b8e83c1575b7c5d81f0e

It works few seconds correctly:
Packet captured!
PACKET: 54 bytes, wire length 54 cap length 54 @ 2014-06-16 23:58:26.339531 
+0400 MSK

SrcMAC=00:1b:21:b8:7f:52 DstMAC=28:c0:da:46:7e:94 EthernetType=IPv4 Length=0}
- Layer 2 (20 bytes) = IPv4 {Contents=[...] Payload=[...] Version=4 IHL=5 TOS=0 
Length=40 Id=0 Flags=DF FragOffset=0 TTL=64 Protocol=TCP Checksum=38040 
SrcIP=178.63.152.142 DstIP=186.2.161.103 Options=[] Padding=[]}
- Layer 3 (20 bytes) = TCP  {Contents=[...] Payload=[] SrcPort=21(ftp) 
DstPort=22(ssh) Seq=0 Ack=2226600473 DataOffset=5 FIN=false SYN=false RST=true 
PSH=false ACK=true URG=false ECE=false CWR=false NS=false Window=0 
Checksum=19101 Urgent=0 Options=[] Padding=[]}

But fail with stacktrace:

Hey, Pavel,

Sorry for the late reply, I missed the initial creation of this bug.  Could you 
do me a favor and pull down the current master?  I don't think the bug is 
fixed, but I'm hoping the line numbers will match up better.
