Hello Wireshark Developer,

the current version of Wireshark crashes if snooping NFS filehandles is
enabled.

I would share the pcap file to reproduce the issue within a private email.

Steps to reproduce:
1. Delete existing wireshark profile e.g. C:\Users\<your
username>\AppData\Roaming\Wireshark
2. Load attached pcap file "crash_nfs_snoop_fh.pcap"
3. Open NFS protocol preferences and select "Snoop FH to filename mappings" and
"Snoop full path to filenames"
4. Sometime Wireshark crashes immediately, sometimes during an immediate exit

5. Open pcap file again and check protocol preferences if both snoop settings
are selected
6. Wireshark crashes on exit again

The old version 1.12.8 is not affected.

Regards,
Carsten
