Hi.
Out of interest, are there supposed to be issues with Ethernet Pcap-NG
files/packets appended to other Pcap-NG files generated with Wireshark 1.0.7
having an unrecognised link type in later (SVN) versions of Wireshark? At
the same time, it seems that 1.0.7 has issues reading packets in Pcap-NG
files from later versions (i.e. it'll try to recognise a few frames, and if
the link type is Ethernet, show them in the packet pane, but it'll complain
about a decompression error when trying to view them, or it'll just show one
packet with an unknown link type (usally 0 or 113 here), depending on how
packets were combined).

I've attached some samples for reference.

Thanks,
Tyson.
