Not quite, check frame #256 

./tshark -r /tmp/fuzz-2013-05-25-10691.pcap -R 'frame.number == 256' -O

...

let's grep -v 257

  [Frame: 15, payload: 3598-3598 (1 byte)]
  [Frame: 22, payload: 5141-5393 (253 bytes)]

  [Frame: 206, payload: 52191-52420 (230 bytes)]
  [Frame: 241, payload: 61159-61159 (1 byte)]
  [Frame: 254, payload: 65015-65015 (1 byte)]

It seems for me that:
 a/ there're more than 256 fragments (260)
 b/ some fragments don't have 257 bytes.
