bridge and netfilter, IIRC this was also the problem last time.

Do you have any ebtables loaded?
Never heard of them, but making a cursory check just in case..

brad@srv:/raid10/src/linux-2.6.39$ grep EBTABLE .config
# CONFIG_BRIDGE_NF_EBTABLES is not set

Can you try building a kernel without ebtables? Without netfilter at 
all?
Well, without netfilter I can't get it to crash. The problem is 
without netfilter I can't actually use it the way I use it to get it 
to crash.

I rebooted into a netfilter kernel, and did all the steps I'd used on 
the no-netfilter kernel and it ticked along happily.

So the result of the experiment is inconclusive. Having said that, the 
backtraces certainly smell networky.

To get it to crash, I have to start IE in the VM and https to the 
public address of the machine, which is then redirected by netfilter 
back into another of the VM's.

I can https directly to the other VM's address, but that does not 
cause it to crash, however without netfilter loaded I can't bounce off 
the public IP. It's all rather confusing really.

What next Sherlock?
Maybe the Sherlocks at netdev@ can tell.
