Hi Pat,
i’ve just run a test http://www.webpagetest.org/result/131001_QE_D37/ and the results were not captured.
I’ve found this happens any time i use ?mmcore.gm=2 at the end of the URI stem.
I use that incantation to stop any MVT that might be running from affecting the test results, but every time i use it i get a “The test completed but there were no successful results.” message.
i think the ?mmcore.gm=2 is futzing with your parsing somehow.
