When running a server with:

yeti --wd-url http://localhost:4444 --server --loglevel debug

And then running tests with:

yeti --browser chrome --browser firefox mod/quiz/yui/src/autosave/tests/unit/autosave.html

Sometimes we see the following output:

I'm seeing this at other times too, and I'm having difficulty writing a testcase that easily reproduces this. It looks like some requests come through after an test has completed and the agentId disposed of. As a result, the this.agents list is null, and the test bombs out.

This only seems to happen with firefox, and from what I've seen, only seems to happen with two or more browsers running.

I meant to add, at the time that this happens, we get the following displayed in Firefox:

Internal Server Error
undefined

Fixed in a9528c2. Thanks for the report!

(That commit message's reference to issue 79 is incorrect. I've added a note to the commit with corrected information.)
