Hi,
I had the same problem too. I had Dave installed and working, then I installed NetBarrier. And ever since then, every time I tried to use Dave (either to connect to a Win share, or have a Win machine connecting to OS X share), I get a kernel panic, which I think is the same as you are getting, where I get a lot of code on my screen...
I never found a way to solve this, so I had to reinstall X from scratch...
Hopefully someone here has a better solution than mine...
