The attached wifi trace file will trigger Wireshark to crash with a GTK message
similar to:
> (wireshark-bin:53858): Gtk-WARNING **: gtktextbtree.c:4019: byte index off the end of the line
> Gtk-ERROR **: Byte index 37 is off the end of the line
To replicate:
1 - Open the attached 8 packet trace file.
2 - In the Packet Details window:
3 - Expand tree: "802.1X Authentication"
4 - Expand tree: "Extensible Authentication Protocol"
5 - Expand tree: "[8 EAP-TLS Fragments ...."
6 - Select item "[Frame 4, payload...." or higher and Wireshark will crash with
the "Byte index XX is off the end of the line" message.
This same issue was replicated on Windows XP system.
Note that the frames in this trace are NOT in fact all related EAP-TLS
fragments.
