I haven't given a thought to dead spots in the 13 years I've been playing, so naturally I had to try my two basses when I got home today.
And sure enough, there was a hint of death on fret 7 on the G string. As well as in a few other places. However, what I noticed was that these largely disappeared as long as I was diligent with my floating thumb technique. Which isn't surprising, since the D played on the G-string causes massive sympathetic vibration in the open D-string, which steals the energy very quickly. If the strings are properly muted (as with the floating thumb), that doesn't happen.
I'm not saying this is the single factor in dead spots, but it could explain why some almost always have them, while others have never noticed it.
