Have you traced the crash to libpcap or Ethereal? Any info would be
helpful to either group, either us or the folks at www.tcpdump.org.

But, no, stdin won't work.  Ethereal makes a first pass through a trace
file and reads all the frames. That gives you the list of frames in the
top pane of the GUI.  Each frame's location in the file is remembered.

After that, when you click on a frame's row in the GUI list, the file
is read in a random-access fashion (ignoring what zlib has to do to go backwards
in a trace gzipped file...) to read that packet. So, the random-access
reading is incompatible with the stdin stream.

That's the "update packets in real time" option that goes along with
the -k command-line option.
