Second bug:
The error occurs when you flip the hardware wifi switch at the front
of the computer to the off position and run "nmap --iflist". The error
is a failed assertion. This one is a little wired, I got a few of my
friends to test it out and they had mixed results, some hit the bug,
some didn't. It was tested on two R60's and a T60, both R60's
experienced the error while the T60 didn't.

I'm writing a patch for it right now but I would like it if some other
people with laptops that have hardware wifi switches tested this out.
  
Hi,

I tried it on a Z61 with XP SP3.
I had Nmap 4.23RC3 installed and when I turned the hardware wireless
switch off I saw that --iflist IP address for that adapter reported as
"(null)" and got a warning about no interface for route to 255.255.255.255
I installed 4.65 and tried --iflist twice after turning off the hardware
switch.  The first was mere seconds after flipping the switch and
--iflist showed the interface was down. The second time was a few
seconds later and I got the assert failure.  See attached.
