Hi all,

Attached is a sniffer trace that will hang 0.9.5 because the protocol
field in the IP header (0x47) is bad.
In fact, parts of the IP header is erronous. Everything works fine when
I change 0x47 from the erronous 0x2e
to 0x11 (UDP)

Perhaps ethereal should stop parsing when it realises that the packet is
erronous.

Alex.
