This orange became much more frequent after bug 769254.  I don't know why but I saw an existing leak turn permaorange with that bug; the leak was triggered (in part) by this test.

So although I don't know why bug 769254 tickles this randomorange, this bug is now blocking the most important browser-api bug we have.  We either need to fix this test, fix whatever code happens to be broken, or disable the test.  And we need to do this now.

Mounir, you wrote this test; can you try to fix it?  I doubt that the increased orange frequency here is due to a bug in my patches, and I can't reproduce the orange on my Windows VM, with or without bug 769254.
Severity: normal → blocker
I'm not sure whether it's significant, but bug 769254 caused timeouts in several tests besides this one, which suggests a different failure mode than the ones above:

Something made that bug happening a dozen time a day while it was happening once every few days :(
IME, randomoranges sometimes get tickled into being more or less random by entirely innocent code.

I think someone needs to actually fix this test.
