6-stable and Tcpdump problems

I am using the latest FreeBSD 6-stable and I am still having trouble 
dumping tcpdump in clear text data.
In FreeBSD 5.x using 'tcpdump -A -s 0 -i sk0' I would always give me a 
full screen Ascii dump of current network data to the screen but now it 
just shows everything in Hex.
I submitted a send-pr on this sometime around 6.0 release but it never 
got anywhere.
If you use the same command on 5.x it works fine.
I found the closest thing I can get is using tcpdump -XX -s 0 -i sk0 
which dumps both Hex and Acsii anything with the '-A' which is normally 
the important flag always results in Hex dumps.
Installing ngrep from ports and doing 'ngrep -d sk0' gives me the result 
I want but I have found over time that ngrep often fails to work 
depending on when I track 6-stable, I would prefer to use tcpdump always 

Can any one agree with me there is a bug here? I have the same result on 
multiple machines.
