Still exists in latest snapshot. I noticed the duplication also occurs if you stand in the same chunk in the repro world; there may be some conditions to it as I didn't observe this in a previous repro environment.
Also attaching log file, which has some nice long stack overflow exceptions that were ignored when loading. Last level load in the log is related to the screenshot.
Attaching crash report.
I should mention also that we originally discovered this issue accidentally in a multiplayer world: Besides the minimal repro, if you nether-portal in to an adjacent chunk in an area away from spawn (rather than just loading a single player world standing in an adjacent chunk) it also triggers the bug (and may crash the server, I think depending on the number of entities it results in)
