b2g_emulator_vm mozilla-inbound opt test marionette-webapi on 2014-08-07 00:42:35 PDT for push 73e945ea5a4c
slave: tst-linux64-spot-108

We appear to have a case of marionette not responding, which causes a TimeoutException, and thus a failed test - however we finally do get a response and then complain that a test_end was logged while a test was not in progress. We then also get a "AttributeError: 'NoneType' object has no attribute 'exc_info'" later.

Could we handle this case any better? :-)

Looking at this error I think that mozdevice has some race condition, or at least with the logging. The NoneType error from the stack and logging appear to be from MozDevice

So can we handle this better, I dont think we can from marionette but probably from Mozbase

And another:

I'm guessing this is a regression from bug 956739.

This looks quite a bit like bug 1036565. I think the error message is pretty informative, but if it's irrelevant in context maybe we should change it.
