#37 Client can SEGV.

Client SEGV's at line local.c:571:
for(x = minx;x <= maxx; x++) {
for(y = miny;y <= maxy; y++) {
->> if(terrainInfo[x*250+y].types) {

Somehow we get to this point with terrainInfo == NULL.
I
hacked around it by enclosing outer loop in
if(terrainInfo)
but that's obviously suboptimal.
