Build Information:
Version 1.4.0rc1

Copyright 1998-2010 Gerald Combs <gerald@xxxxxxxxxxxxx> and contributors.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Compiled with GTK+ 2.18.6, (32-bit) with GLib 2.22.4, with libpcap 1.1.1, with
libz 1.2.3, with POSIX capabilities (Linux), with libpcre 7.9, without SMI,
without c-ares, without ADNS, without Lua, with Python 2.6.4, with GnuTLS
2.8.6,
with Gcrypt 1.4.5, without Kerberos, with GeoIP, with PortAudio V19-devel
(built
Aug 19 2009), without AirPcap.

Running on Linux 2.6.30-gentoo-r8, with libpcap version 1.1.1, with libz 1.2.3,
GnuTLS 2.8.6, Gcrypt 1.4.5.

Built using gcc 4.3.4.

--
Choosing 'Show all streams' from the RTP section of the telephony menu,
choosing a stream and clicking 'Analyze' gives the RTP Stream Analysis window
but all the packets have 0.00 in the Delta column, meaning the filtered jitter
is always 0.00. The skew also has 0.00 for all packets. IP BW appears to be
correctly set.

Expected: The delta column should contain the time difference in milliseconds
between the time at which packet n was detected and the time at which packet
n-1 was detected.

Actual: All Delta values are 0.00.

Same in wireshark 1.2.8 and 1.2.9
