Is Nmap itself actually crashing/quitting? If so, then I think we should at least handle this more gracefully. Printing a useful warning message is fine, and probably desirable to help us track this issue. I guess continuing with OS detection without that probe seems reasonable, though in that case we should probably mark the fingerprints as not good so we don't ask the user to submit them.
Yes, Nmap was quitting with pfatal at this point. r33619 should allow it to continue, but marks the whole fingerprint as "incomplete" which prevents it from being suggested for submission. The fix was a bit more invasive than I would have wished (new bool members for FingerPrintResults and FPHost), but it should work no matter what probe fails to be sent. The error message regarding the contents of the probe is still presented, just changed to not be fatal, so we can debug these issues in the future if necessary.
