Intermittent WebKit Crash

Hi there,

We are getting an intermittent WebKit crash when a user clicks on a button form control that reloads the page.

Our application is a Carbon/CFM application.

Below are 2 crash logs. Does it make sense to anyone Apple? Given that it is low frequency intermittent crasher, it is especially nasty.

As always, thanks for any assistance.

Charles
