Here's my capture. Captured on Win 7 x64 Pro with NM 3.4 (3.4.2350.0). Tried to load in to Wireshark x64 1.5.0-SVN-33615 with the error I reported previously. The capture has DNP3 traffic on port 2000 captured on a PPTP VPN.
OK, the per-file link-layer type for the file is 1, meaning Ethernet, but the per-packet link-layer type for most of the packets is 0. That's probably a quirk either of VPN captures or general PPP captures.
I've checked into the trunk and 1.4 branches a change to treat a link-layer type of 0 as Ethernet; that allows it to read your capture.
