Hm. This looks like a watchdog timeout, but the stack traces have no symbols, so I can't really be sure. :(

Geoff, any idea why we don't have any symbols for these stacks?


Although I'll admit these lines look a bit worrying:

Probably not related to this test, but we should try to figure out why that's happening. Nothing should be calling that function with a null observer. There are only a few callers:

There seems to be a problem with symbols for Android xpcshell crashes - bug 1389805 - but I don't have further insight.
