[Garrett Kajmowicz <garrett.kajmowicz@xxxxxxxxx>]

I'm running Ubuntu. I used Wireshark (package: 1.12.1+g01b65bf-4+deb8u2build0.15.04.1) to capture an NFS packet trace, attempting to understand some latency issues with some applications. Packet trace came out to about 35 MiB.

Attempting to load the packet trace failed repeatedly. Using the commandline

wireshark -r /u/garrettk/capture2 -n

resulted in a core with the backtrace:
