Hi,

It's possible to crash wireshark with null dereference of data_val.
Attaching sample capture file.

Reverting r43230 (bug #3317) fix the problem.

If you run tshark please note that crash will occur on second dissection of
packet. i.e. tshark -r /tmp/test won't crash, but tshark -r /tmp/test -2 will.

Or skip -2 and just run wireshark.
