First, please answer a couple of "obvious stupid" questions:

1. What system are you trying to run it on?
2. What is your wine version?
3. Do you have the latest winetricks?
4. Are you using a new clean prefix?
5. What version of NVSE are you using?

A shot in the dark: try switching off the ptrace_scope parameter in the kernel:

echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope

1. ubuntu 13.04
2. wine-1.6
3. of course
4. should be obvious from my previous comment
5. the latest, the author hasn't updated it for more than 12 months now.
6. /proc/sys/kernel/yama/ptrace_scope already relaxed

But all this is irrelevant. Because you actually need to first load up Steam in the same prefix, then you can run this.

Not necessarily, NVSE is capable of running Steam on its own. Can you run New Vegas without NVSE?
