Attempting to expand an iframe node, in the elements tab in web-inspector, causes webkit to crash. Note that the bug does not occur in all cases i.e. here: http://developer.yahoo.com/yui/examples/editor/toolbar_editor.html Perhaps because in the yahoo example the iframe does not use the 'src' attribute?
Have looked a it further, the crash occurs even without the src attribute. Perhaps the yahoo example is immune, because the iframe was generated somehow? There is no reference to it in the html I can see. A further reduction: <html> <head> <title>untitled</title> </head> <body> <iframe/> </body> </html>
