Fyi, I followed these instructions to install an updated kismet on an HD install of backtrack:

Use Subversion to Download Source:

svn co kismet-devel
CD Into the Directory:
cd kismet-devel
Configure Without SUID:
./configure --disable-setuid
Make and Install:
make && make forceinstall

I then edited /usr/local/etc/kismet.conf and added:

i also updated the madwifi drivers as well by following this:

Use Subversion to Download Source:

svn checkout madwifi-ng
CD Into the Directory:
cd madwifi-ng
Remove Old Modules:
rmmod -w ath_pci.ko
Note: If you get an error with this just ignore it.
Make and Install It:
make && make install

I'd love to be helpful but I'm quite new to all this linux stuff. What is gdb? What is the difference between normally running kismet (i.e. typing kismet from root) and standalone kismet_server in gdb? Where will I see the initial crash message and the output of 'bt' in gdb?

Sorry for all the 'noob' questions... i'm learning so much each day it makes my head spin sometimes.
