Looks like a null pointer. Reading the same trace file in 0.9.15 works, this version 
doesn't. I've added a text attachment of the same to prevent line wrapping.

I cannot release the trace file but it is a switch capture from a Win2K box. Lots of 
SMB, TNS, Web etc.

Drop me a line if you have any Qs.
