When moving a column with at least one packet in the packet list, a
use-after-free occurs somewhere in the GTK library. Maybe it is a GTK bug, but
a workaround is available.

Steps to reproduce:

randpkt -c 1 rand.pcap
wireshark-gtk -r rand.pcap
move a column (say, Time) to the left/right
crash!

This crash is 100% reproducible when GTK is built with ASAN, otherwise it may
occur less frequently (one out of three maybe?)
