Stack trace attached (can't copy it out of console.. :() Steps to reproduce: 1. Open a single frame webpage 2. Open web inspector 3. Select any resource in the resources sidebar panel, or switch away from the DOM tree content view. 4. Reload the page This doesn't happen if reloading when the main frame resource's DOM tree content view is displayed, or if selecting a resource and navigating to a different page. I think there is something causing the same content view to be entered into the backForwardList twice, or more than one content view thinks it is displayed at the same time. A brute force fix is to simply hide all visible content views before disassociating from them (rather than only hiding the content view associated with the 'current' history entry), but this feels like ignoring the root cause.

This seems related to the fact that there are nested content view containers and histories. However it's not clear why one list has two visible entries, as the nested histories don't touch each other.
(In reply to comment #0) > Stack trace attached (can't copy it out of console.. :() Hmm, this should work by either selecting the row and Cmd+C or drag to select the text.
