Reported 2014-12-08 16:58:31 PST
To reproduce: 1. Navigate to a page with many resources, say http://twitter.com 2. Open the inspector 3. Select resources repeatedly in the resources tab. Reselecting ones that have already been selected and loaded is fine. After a little bit of this, the inspector will crash and close.
