Just a regular safety belt. We still have quite a few places with mapBlockIndex[somehash] which can potentially insert an entry if we screw some checks up somewhere (should really get rid of these [] some day). Won't hurt to double-check imo.

Ah ok, was already worried that I misunderstood mapBlockIndex when I used it in various places. An easy way to get rid of the [] is to use .at() as a replacement as it throws an exception when you try to access a non-existent item, instead of creating an new item as with []. Better to crash early in such cases.
