Compiled (64-bit) with GTK+ 2.22.1, with GLib 2.26.1, with WinPcap (version
unknown), with libz 1.2.5, without POSIX capabilities, without libpcre, without
SMI, with c-ares 1.7.1, with Lua 5.1, without Python, with GnuTLS 2.10.3, with
Gcrypt 1.4.6, without Kerberos, with GeoIP, with PortAudio V19-devel (built Jan
10 2012), with AirPcap.

Running on 64-bit Windows 7 Service Pack 1, build 7601, with WinPcap version
4.1.2 (packet.dll version 4.1.0.2001), based on libpcap version 1.0 branch
1_0_rel0b (20091008), GnuTLS 2.10.3, Gcrypt 1.4.6, without AirPcap.

Built using Microsoft Visual C++ 9.0 build 21022

System: Windows 7 x64
Software version: Wireshark Version 1.6.5 (SVN Rev 40429 from /trunk-1.6)
Note: Wireshark running as administrator

[See PCAP Capture attachment]

Steps for bug repro:

- Open capture file (File -> Open) [There is only one HTTP frame]
- Make sure "View -> Packet details" is checked
- In "Packet Details" view: Unfold "Line-based test data: text/html"
    - The unfolded line reads: "<h3 align center"> ..."
    - Left click on this line
    - Right click -> Copy -> Value
- *crash*

I do not have PDB files for Wireshark so I can't provide a meaningful dump. My
guess is that the crash is due to the fact that the HTML line contains ASCII
characters and binary data.
