Repetitive crashing due to "tessellating block in world"

Incomplete without a crash report from ([minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/finding-minecraft-data-folder]). Please attach it so that we can diagnose your issue.

These are all of them.

Also, your Java is very horribly out of date, I would strongly suggest updating your Java to the latest version (1.7.0_65): http://www.java.com/en/download/.

• When using a 32-bit browser on a 64-bit operating system 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.
