What steps will reproduce the problem?
diam = dpkt.diameter.Diameter(eth.ip.tcp.data)
diam.avps
[AVP(code=263, flags=64, len=38, data='ggsnv9vlz1;3511161808;190;6943'),
 AVP(flags=1, len=147456, data='\x00\x0c\x00\x00\x00\x04\x00\x00\x01\x08@\x00\x00\x12ggsnv9vlz1\x00\x00\x00\x00\x01(@\x00\x00"ggsnv9vlz3@movistar.com.ar\x00\x00\x00\x00\x01\x1b@\x00\x00#vlzfedsdp2c@movistar.com.ar\x00\x00\x00\x01\xcd@\x00\x00\x0fcontext\x00\x00\x00\x01\xa0@\x00\x00\x0c\x00\x00\x00\x02\x00\x00\x01\x9f@\x00\x00\x0c\x00\x00\x07)\x00\x00\x01%@\x00\x00\x13vlzfedsdp2c\x00\x00\x00\x01\x16@\x00\x00\x0c\xd1<\xf76\x00\x00\x007@\x00\x00\x0c\xd1P+\xc4\x00\x00\x01\xbb@\x00\x0...........
the First AVP is fine, but the second is not. Because it doesn't skip the 
filling bits from the first AVP to generate it.

What is the expected output? What do you see instead?
this sould be the second AVP
AVP(code=258, flags=64, len=12, data='\x00\x00\x00\x04')

What version of the product are you using? On what operating system?
1.6

Sorry for my english

Here is the problem:
while self.data:
            avp = AVP(self.data)
            l.append(avp)
            self.data = self.data[len(avp):]
        self.data = self.avps = l

when data is splited, it should be done counting the filling bits
