This has got to be one of the weirdest computer bugs I’ve ever seen. The initial bug report stated that typing ‘File:///’ (without the quotes) into almost any app causes the app to crash, on any Mac running any version of OSX 10.8. If you choose to see the Problem Report, that crashes too. Weird. I tried it on a new 15″ Retina MacBook Pro running 10.8.2 and yup, crash-tastic. Although, and I love this, Final Cut Pro 7 will not crash. The old beast.
BTW, don’t email or message someone, hoping to see their computer crash. One forum member at MacRumors did this with the Messages app and it worked, but Messages refused to launch again. He had to go in and delete the message history in the Library, just to get Messages to open again.
