No, there's an issue here.
Under 1.4.2, that seeds locks Minecraft up on two separate machines. Under 1.4.1 it was fine.
Confirmed for me. Seems to hang on "Converting World".

That's already fixed. See MC-767
Oh wow, I can confirm this, Minecraft's been at the "Converting World" screen for about 10 minutes now and not responding. Locked up alright!
Is indeed a duplicate - the crash report was sneakily hanging out in the crash reports folder without displaying. Closed!
@Jon You are correct there is an issue and it does lock up on that seed. However I still have to say this is one of the most poorly written bug reports I have seen in a while. Usually the mods will simply close these as they do not follow The Bug Report Guidelines Here.
@kumasasa Agreed, duplicate of MC-767
This is not a bug report. At the best it's a feature change suggestion, and a poorly written one at that.
