I'm getting this at least once a day on packet traces I run. There are two
scenarios: 

1) Run a trace, save the file and open in Wireshark. It doesn't appear to
matter the size of the trace, the message pops up in a DOS box with "Press any
key to continue". After you press the "any" key (:-) the DOS box and Wireshark
crash.

2) With a trace in progress, the message pops up in a DOS box with "Press any
key to continue". After you press the "any" key (:-) the DOS box and Wireshark
crash.

The saved trace files are unuseable as they will crash Wireshark. If there is a
way to delete the one broken packet, I haven't found it. I know you can save a
range of packets, and I could mark everything before in a range, or everything
after and then merge the files, but I usually end up running another trace and
hoping I didn't miss anything important.

These are four different errors on four different days.
