            Bug ID: 138341
           Summary: Web Inspector: Inspector pauses 3 times when
                    evaluating window.decodeURI('%%%')
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal

* SUMMARY
When pausing on exceptions is enabled, Web Inspector pauses 3 times when evaluating window.decodeURI('%%%')

* STEPS TO REPRODUCE
1. Inspect any page
2. Enable Break on All Exceptions
3. js> window.decodeURI('%%%')
  => have to continue 3 times

* NOTES
(1) is the URI Error inside of the InjectedScript's eval(...)
(2) is the call site of the eval in the InjectedScript (var result = evalFunction.call(inspectedGlobalObject, expression);)
(3) is the last statement in the finally block in the InjectedScript catching the exception.

Mark, I think this might be JSC::Debugger pausing too many times for a single exception.
