In trunk the inspector is frequently crashing (goes white). When that happens if I close the window and attempt to reopen it, I get uncaught exceptions: Resources/Base/Platform.js:27:32: CONSOLE ERROR ReferenceError: Can't find variable: InspectorFrontendHost

I believe this is fixed. A couple months ago I focused on fixing these issues (crashes, white inspectors) and I haven't seen this in a while. Even forcing killing the Inspector's WebContent process it behaves as expected. Closing.
