Having worked around the bug so that Ethereal doesn't crash, you can now
look at the capture again to see why it is that "trp->param_descrip" was
null in the call to "dissect_response_parameters()".

It appears that this would happen only if the request corresponding to
the reply whose dissection caused the crash were short (captured with a
short snapshot length, or not reassembled), so that the descriptor
string wasn't present; was that the case?

If so, the correct fix is not to call "dissect_response_parameters()"
if "trp->param_descrip" is null.
