I hit on it in my post in this thread, and you didn't address one one the important details here. Let me repeat:

Floor[] seems to have no trouble with other hairy expressions that happen to equal integers, for example "((-1)^(1/3) + (-1)^(2/3))/Sqrt[-3]". But a mere Simplify[] reduces that to 1. Perhaps that's where the real bug is. Does Floor[] try Simplify[]? Maybe Simplify[] should be transforming things like Log[100]/Log[10].
