from Peter Wu
Here is a diff of the backtraces in packet 51 of test.pcap
--- test.pcap frame 51 - first record
+++ test.pcap frame 51 - last (fragmented) record

Possibly noteworthy is that the last full frame has more_frags=0 (and
desegment_ssl operates on the decrypted payload). I think that the problem is
related to bug 3303.
