Bukkit

Teleporting between worlds crashes some clients!

Minecraft server: Spigot 1.8.3

Crash detected on two Dell / Debian Wheezy (linux) clients, teleports work fine on Surface Pro 2, Surface Pro 3 / Windows 8 clients. Linux clients are using Oracle java 1.8.

Plugins:

Essentials
MultiWorld
Location Teleport
WorldEdit
WorldGuard
PermissionsEx
StarterKit

What steps will reproduce the problem?
1. Define a new creative world
2. Issue command '/goto creative'

--OR--

1. Define teleport (LocationTeleport plugin) from a survival world to a creative world. Loc1 in survival, loc2 in creative.
2. Run over teleport loc1

What is the expected output? What do you see instead?
The loading screen shows but rather than eventually popping up with the new world location, the client disconnects and remains in the loading screen! Once you restart the minecraft client again, you can teleport from creative back to world as expected but attemting to teleport back from world to creative crashes the client again in the same way.

What version of the product are you using?
5.2.6

Do you have an error log of what happened?
No

Please provide any additional information below.
Server log only lists that the user disconnected at the time of crash. No errors. Same for client logs.

Thx for the correct bug report, I really think this problem is caused by some problems on that platform, can you try if it also happens with other multiworld plugins, as the bukkit api is the platform that actually moves the clients
