In those cases, and apparently in this one too, an error occurs in the heart of the browser's networking code, but what gets back to the XHR handler is garbage. The linked bug in the linked bug indicates that the result of the request is:
xhr.onerror is called with xhr.status == 0, xhr.readyState == 4 readyState=4 means that the request is complete, which is when we're supposed to look at the status code. xhr.status=0 is meaningless information. Unfortunately, there's not a lot that qooxdoo can do to help you with this. My suggestion would be to use wireshark or some similar protocol analyzer, and look at exactly what packets are going back and forth (if any) on the wire. If you can build a sample application that causes this problem, that I can reproduce with chromium on Linux (I'm currently using 4.0.249.30 (Ubuntu build 33928)), I do the wireshark trace to see what's going on.
