no a11y in the stack, can we cc for advise?

The crash that's reported is intentional and can be ignored.

Thanks, Josh.

And as always, since our infrastructure doesn't deal well with test failures that cascade into 22000 other failures, it would be nice if there was a way to restrict the output here, like failing just once per test if gA11yEventListeners is undefined. http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1308050035.1308051205.3907.gz Rev3 Fedora 12 mozilla-central opt test mochitest-other on 2011/06/14 04:13:55 s: talos-r3-fed-046 308 ERROR TEST-UNEXPECTED-FAIL | chrome://mochitests/content/a11y/accessible/actions/test_tree.xul | [SimpleTest/SimpleTest.js, window.onerror] An error occurred - uncaught exception: [Exception...

Alex, could you please look into this test failure?

(In reply to comment #12) > Alex, could you please look into this test failure? it seems the failure was scared by your asking :) let's get back to it if it decides to appear again.

Indeed!
