Compiled (32-bit) with GTK+ 2.24.10, with Cairo 1.10.2, with Pango 1.30.0, with
GLib 2.32.2, with WinPcap (4_1_2), with libz 1.2.5, without POSIX capabilities,

V19-devel (built Jun  6 2012), with AirPcap.

Running on Windows XP Service Pack 3, build 2600, with WinPcap version 4.1.2
(packet.dll version 4.1.0.2001), based on libpcap version 1.0 branch 1_0_rel0b

Built using Microsoft Visual C++ 10.0 build 40219

--
The UMTS GTP QOS PROFILE under the AVP 3GPP-GPRS-Negotiated-QoS-profile in
Diameter messages is not correct for Release 8 or higher. According to the 3gpp
specification TS 29.061 (v9.6.0), for Release 8 or higher version QoS, the QoS
information should contain: -QCI -ARP -GBR QoS Information (MBR, GBR or
APN-AMBR)

However the Wireshark decode the Release 8 QoS as: UMTS GTP Qos Profile:
-Version -Hyphen separator -Spare -QoS delay -QoS reliability
which always result in a malformed packet, so it's impossible to read the
following AVPs.
