[AC-2905] HttpClient "bound" callbacks not working

Creating an XHR with: var xhr = Titanium.Network.createHTTPClient() and then setting the callback with: xhr.onreadystatechange = this.func.bind(null, this) Following the "xhr.send(data)", I observe the proper TCP packets being sent to the server and the proper response coming back from the server. However, immediately following the "xhr.send(data)", the system throws: E/KrollCallback( 314): (kroll$1: app://app.js) [282,3299] Error, invocation: [callMethod Network.HTTPClient.(anonymous) org.appcelerator.titanium.kroll.KrollCallback@45118288], message: null E/KrollCallback( 314): java.lang.IllegalStateException E/KrollCallback( 314): at org.mozilla.javascript.ScriptRuntime.getTopCallScope(ScriptRuntime.java:3159) E/KrollCallback( 314): at org.mozilla.javascript.BoundFunction.call(BoundFunction.java:82) E/KrollCallback( 314): at org.appcelerator.titanium.kroll.KrollCallback.callSync(KrollCallback.java:139) E/KrollCallback( 314): at org.appcelerator.titanium.kroll.KrollCallback$1.run(KrollCallback.java:164) E/KrollCallback( 314): at android.os.Handler.handleCallback(Handler.java:587) E/KrollCallback( 314): at android.os.Handler.dispatchMessage(Handler.java:92) E/KrollCallback( 314): at android.os.Looper.loop(Looper.java:123) E/KrollCallback( 314): at org.appcelerator.titanium.kroll.KrollHandlerThread.run(KrollHandlerThread.java:86) If I remove the bind from the callback function then it works as it should (except that I don't have "this" in the parameter list of the callback.
