Both Wireshark and tshark will terminate with a runtime error when a tracefile
with edp packets is read and one of the following two display filters is
applied: edp.info==<something>, or edp.unknown==<something>.
The debug message generated by both Wireshark and tshark using either display
filter report the same "Unhandled exception" at tvbuff.c line 631...
> $ tshark -r edp-frames.pcap -R edp.info==a
> Unhandled exception ("tvbuff.c:631: failed assertion "tvb && tvb->initialized"", group=1, code=4)
>
> This application has requested the Runtime to terminate it in an unusual way.
> Please contact the application's support team for more information.
