I hit an assertion failure when i trigger an exception in the inspector console. To repro: 1. Open google.com in a debug build 2. open the web inspector 3. open the console 4. type 'a' (or some other non-existant variable) and hit enter

This no longer reproduces, but null is shown where there should be an exception.
Fixed the new symptom in r41353.
