Crash Experimental Rust

This is the error: http://gyazo.com/c12ad122a8e27602cc7ed87d33bc93b3

Someone can help me?

Too hard to say what this could be. Id post it up in the bug reports that would be the quickest way…

No, we can’t. Paste the contents of that error log to pastebin and link it here, and we might be able to help you.

Just telling us that an error log is being created says nothing.
