Using /tellraw to linkify a link in Minecraft, clicking the link, crashes

I was looking to find a way to linkify this link with the commands, and Dinnerbone suggested minecraftjson.com. I created the command, pasted it into the command block. I placed a button on the command block, and ran it.

I clicked the link from the command that I pasted, and Minecraft suddenly crashed.

If you go to minecraftjson.com, and use its interface (I'm sure you'll understand it) to create the command, Copy the command, then load up your Minecraft world, give yourself a command block, place it on the ground, right-click the command block, paste the command, put a button on it, right-click it, it will crash as shown in the crash report.
