           Summary: XSS Auditor interferes with -[WebView
                    stringByEvaluatingJavaScriptFromString:]
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW

          Severity: Normal
          Priority: P2
         Component: WebCore Misc.

I tracked down an assertion failure in DumpRenderTree this afternoon that is
caused by the XSS auditor causing the following API invocation to fail:
[webView stringByEvaluatingJavaScriptFromString:@"0"];  With the XSS auditor
enabled, this returns the empty string rather than "0" as expected.  This was
being tripped over by DumpRenderTree on machines that had never run the layout
tests before due to the default preferences being incorrectly configured
(<http://trac.webkit.org/changeset/46304>), but it seems undesirable for the
XSS auditor to have any effect on these sorts of APIs.
