Loaded a capture file containing *only* the packet in question, or
loaded the capture file from which you extracted that packet?

If the latter, there may be another bug, which is in the CVS tree but
not in 0.8.18.

If the former, the problem doesn't occur for me.

Can you get a stack trace from the core dump, so we can see where it's
blowing up?
