I just installed tPacketCapture
(https://play.google.com/store/apps/details?id=jp.co.taosoftware.android.packetcapture&hl=en),
a relatively well-rated Android app that ostensibly allows for packet capture
without root. When attempting to read the generated PCAPs in 1.12.0 on a
Win7-32 VM, I got consistent crashes, a la:

I admit to not having any debugging tools on that particular VM, nor a great
deal of interest in installing them all to the point where I could effectively
trace this myself. I figured you'd want to know, though, in case there is a
security implication here - there have been a lot of root-level compromises
reading file formats over the years. :-P

Happy to work with you guys to reproduce as necessary, just let me know what I
need to provide.
