Bug crash-report

In this video : https://www.youtube.com/watch?v=pDIc_4U3Guw
You can see a "bug" , the crash report write all the coordinates of players. It's a realy major problem for any PvP server. Have you an idea how we can resolve that ? Can you fix this ? We need a plugin ?
Sorry for my bad english, it's not my natural language.

Thanks !
