Running tshark -V -n -R 'kerberos.error_code == 7' port 88 eventually causes
tshark to exit with Unhandled exception (group=1, code=6).

I've been able to leave tshark running while inspecting other protocols and it
does not appear to exit with the unhandled exception.

I was other posts about this possibly being related to an 'out of memory
exception' and have increased the datasize from the default to 2GB.  tshark
appears to die before getting anywhere above 1GB in memory utilization for the
process.

I'm able to get this to happen fairly frequently, so if any additional
information/debugging is required, it should not be a problem.
