Description Brian Burg 2013-11-18 08:36:59 PST 
This has happened to me when using console, occasionally when stepping through inspector code. Most of the crashes happen in InjectedScript.

I have yet to come up with straightforward repro steps, so I'll start by posting stack traces as I run into them.

Hasn't happened to me lately. Will file a better bug if it happens.
