I'm trying to read a 60 MB pcap file, when after fully reading the file, during
disection, Wireshark will trigger a SIGSGV in g_strlcpy.

Backtrace is attached.

The pcap was collected on one of our gateways (Freifunk) and may contain
sensitive information about our users. Therefore I cannot upload it.
