crashlog

OS X 10.6.5

str:
1. load http://hicksdesign.co.uk/journal/finally-a-fluid-hicksdesign
2. open webkit inspector bu either
    * option-command-I
    * right-click on element to inspector and choose 'inspect element'
AR the inspector opens but remains blank, then the browser crashes
ER obviously…

this started *after* svn r71897 (which works fine)

affected: WebKit nightly builds and Chrome 9.0.587.0 dev

the url above is not the only one where it happens, it is the most likely one not to change…

other url that repro the crash:
http://dev.w3.org/csswg/css3-writing-modes/

I haven't been able to find a pattern.
