I encountered this bug in 14w28a as well. I ended up spawning in deep within a wall about 10-20 blocks away from the actual nether portal.
So, when are we going to be seeing any updates on this? Is this issue keeping the next snapshot from being released or something?
Ok this is still annoyingly in 14w31a. I really hate to say this but this bug should have been FIXED by now. Fix it already holy cow. It's a small bug that has enourmous consequences for people, glowstone is already an ultra-high risk thing to get, It's on the ceiling over lava almost all the time and with sea lamps coming up, glowstone is losing its viability as something useful in survival. Sure, you'd need it for redstone lamps but at this rate thats all it'll be used for BECAUSE THERE IS NOT ENOUGH SPAWNING ANYMORE. I mean it's spawning in 1/3rd the amount at best anymore. Fix this bug already. It's been around for months, now and it's a simple typo.
