Minecraft: 1.7.10-pre4 (updated Wed May 14 09:29:23 PDT 2014)
Minecraft crashes when it tries to render a non-existent block (id: 150, but appears to do the same thing with other non-existent blocks too) in the super-flat configuration dialog.
When I set the minecraft super-flat configuration settings to "2;7,150;1;village" and clicked "Use Preset", I expected minecraft to replace the non-existent block with air or reset the super-flat configuration settings to their default.
What actually happened when I clicked the "Use Preset" button after setting the minecraft super-flat configuration settings to "2;7,150;1;village" was a complete crash.
In order to reproduce this crash I would:
1. Open the minecraft "Create New World" dialog.
2. Click the "More World Options..." button and set the world type to "Superflat".
3. Click the "Customize" button and then click the "Presets" button.
4. Change the content of the preset editing box to "2;7,150;1;village".
5. Click the "Use Preset" button.
And then the game crashes.
Hope this helps!
