I hit this opening the Inspector on cnn.com. I can't reproduce right now though.

I've seen this a couple of times, but the exact steps to reproduce the problem are still unclear to me. 

However, it should fixed with https://bugs.webkit.org/show_bug.cgi?id=144982 as I added  "if (sourceCodeLocation)" in WebInspector.CallFrameView.
