FYI today I tried opening a pcap-ng file with wireshark rev 24118, and it 
sort of worked.
What works:
- the first file I opened was a 50+MB file generated with NTAR. Real 
ethernet packets coming from a custom board. Wireshark opened the trace 
without any problem, and the decoded packets made perfectly sense. YAY!
What doesn't work:
- timestamps are wrong. There are two problems here:
 1. the IDB option for the timestamp precision is not decoded, and I was 
generating timestamps with nanosecond precision.
 2. timestamps are not in the libpcap fashion (seconds and microseconds, or 
seconds and nanoseconds). It's a single 64bit quantity that is split into 
high and low 32bits.
Have a nice day
