Sometimes when I find a stronghold or Mineshaft, there are Torches inside. Sometimes with them placed down it is still dark. The torches don't even make light, but when a break the torch and place it back it lights up.
You don't need to break it, just right click the torch to fix it.
Yeah, I'm pretty sure this is a well known bug and is planned to be fixed along with many other lighting bugs in 1.5.
