           Summary: REGRESSION(r41732): Crash when constructing
                    XMLHttpRequest in a detached document
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: Regression
          Severity: Normal
          Priority: P1
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ap at webkit.org


Now that JSXMLHttpRequestConstructor (and other constructors) are tied to a
global object, not to a script execution context, we need to take care of edge
cases where converting from ScriptExecutionContext to JSDOMGlobalObject doesn't
work. Namely, both exist for a detached document, but
toJSDOMGlobalObject(scriptExecutionContext) returns 0.

Patch forthcoming.
