If you load a world while in a minecart the player is gitters back and forth in F5 mode.
How to reproduce:
1. Create a world and get in a minecart. (Doing this on a horse also works)
1.a (Make sure it is moving to get see it better.)
2. Reload the world. Go into F5 mode while in the minecart.

Cannot reproduce.
Edit: Can reproduce.
Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.
The crash reports doesn't tell anything useful, except that your Java is outdated:
Please update your Java to the latest version: http://www.java.com/en/download/ . Keep in mind that when using a 32-bit browser on a 64-bit OS the automatic version detection will only show the 32-bit version of Java, the 64-bit version needs to be downloaded manually: http://www.java.com/en/download/manual.jsp .
Please report if the issue persists with the latest Java version.
Confirmed in 1.5.1 on Linux. See video (because it’s too large, I put in on Youtube).

Are you referring to the fact that the player is higher up in the minecart than they used to be?
