When you open a page containing an applet WebKit will crash if you opened the WebInspector before navigating away from the applet page

I tried this on 3 machines. MBP, MB and MacMini. They all had the problem. Some did not have PithHelmet installed.

Still doesn't crash for me, even on another machine using the steps in comment #3. Is there something else I need to be doing? Download and unzip the test.zip file; open "start.html"; wait for everything to finish loading; open the Inspector; in the same tab/window, go to http://webkit.org/?

You need to open the inspector by right clicking within one of the frames (I had been using the keyboard shortcut), so the real steps to reproduce are: 1. Download and unzip testcase 2. Load "start.html" 3. Right click below white applet area and choose "Inspect Element" 4. Navigate to <http://webkit.org/> ASSERTION FAILED: impl()->frame() (/Users/mlilek/Documents/WebKit/WebCore/bindings/js/JSDOMWindowBase.cpp:774 virtual KJS::ExecState* WebCore::JSDOMWindowBase::globalExec()) Invalid memory access of location bbadbeef eip=03820bd0
