Currently the latest version on their is 18803, as soon as 18804 is there I'll give it a try and let you know.
Unfortunately I do not know much about H.450 other than it is used for 
supplementary services within H.323.
The information below was taken from

     H.450.1 Series defines Supplementary Services for H.323
     H.450.2 Call Transfer supplementary service for H.323
     H.450.3 Call diversion supplementary service for H.323
     H.450.4 Call Hold supplementary service
     H.450.5 Call Park supplementary service
     H.450.6 Call Waiting supplementary service
     H.450.7 Message Waiting Indication supplementary service
     H.450.8 Calling Party Name Presentation supplementary service
     H.450.9 Completion of Calls to Busy Subscribers supplementary service
     H.450.10 Call Offer supplementary service
     H.450.11 Call Intrusion supplementary service
     H.450.12 ANF-CMN supplementary service

Keith,   can you verify this solves your problem?
Also,   there is no page for H450 on the wiki    wiki.wireshark.org
maybe you can add a small page with some information about this

you dont have to wait for the next release.
you can test on win32 using the automatically prerelease builds that
are available from

please try SVN version 18804 or later

Thanks for the capture, Keith.  The problem was with h450 hf fields that
weren't initialised sucessfully (at all in one case, or with non-unique
filter strings in several others) - it was hitting an assertion in proto.c
when an attempt was made to use those fields.

I was able to test by editing packet-h450.c directly, I couldn't regenerate
it from packet-h450-template.c.  I'm attaching a patch to
packet-h450-template.c that hopefully does the same thing. If someone can
generate and check it packet-h450.c in for me I'll retest.
