                    file
           Product: Wireshark
           Version: SVN

Build Information:
The reported problem occurs with the 0.99.5 win32 binary obtained from the
wireshark web site.  I then tried it with the latest SVN build to see if the
issue had already been resolved.  The info for the SVN version is shown below:

Version 0.99.6-SVN-21553 (SVN Rev 21553)

Copyright 1998-2007 Gerald Combs <gerald@xxxxxxxxxxxxx> and contributors.

with GnuTLS 1.6.1, with Gcrypt 1.2.3, with MIT Kerberos, with PortAudio
PortAudio V19-devel, with AirPcap.

The attatched patch (which I will attach momentarily) shows an MGCP VoIP call.
It was captured with a Sigtek DOCSIS sniffer so to view it properly you will
have to check "Treat all Frames as DOCSIS frames" under Edit->Preferences->
Protocols->Frame. 

If I try to perform an RTP analysis of the call (Statistics->RTP->Show all
streams) and then analyze one of the streams, wireshark hangs.
