This bug is still present in 1.8.3
Yes this VERY MUCH is still present (1.8.3)
I had this exact issue happen in a world with no villagers at all, only armor stands (and possibly some zombies), so it doesn't seem to be caused only by villagers.
Also, the silverfish case I had myself was with silverfish that had NoAI:1 so that doesn't seem to be the cause either.
Fairly certain it is some issue with entities not being removed properly by an unloading chunk or something.
Was fixed some time ago with the new block models
Summary and description were wrong: One block has no backface culling and all others do.
Forgot to attach crash report...
Sorry, I did search, but didn't find this report :/
Probably a duplicate of MC-65151
