 We are getting

 "ERROR: invalid channel.(.;)"

 for two New Zealand DVB-T HDHomerun users when trying to scan channels.
 mythtv-setup crashes instead of scanning the channels.

 Problem may be related to http://svn.mythtv.org/trac/ticket/7232, in lines
 249-257 of hdhrchannel.cpp and may be related to use of qam before auto?

 For me this is running 20090806 firmware on mythbuntu 9.10 and fixes
 22824. Also known to occur on 22778.

 Second user running .22 r22824 on Gentoo amd64, HDHR firmware 20091024.

 Seeing these two packets repeated 8,000-13,000 times when beginning a
 scan, after which mythtv-setup segfaults (tcpdump -iwlan0 -vv -s0 -A 'host
 192.168.10.136')

 How can we assist from here?
