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:
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:

crash report for iframe / web-inspector bug
This was fixed a day or two ago.
