Wow, impressing.

The capture file from Jaap is 76kB in size and took more than 10 minutes to
load on my machine!!!

The problem seems to be in desegment_tcp. The len calculated (in packet-tcp.c
line 1105):
len=MIN(nxtseq, msp->nxtpdu) - seq;
is very often just 1, which seems to be odd ;-)

The "again:" label in that function is passed 58834 times which is probably not
a good sign for 101 packets :-)

Maybe someone with more knowledge of that function may have a look at it (I
don't know if the behaviour of that function is in fact intentional)?
