Yes, this might be the same (or the same cause) as bug 854762, which is a reproducible crasher with new code. Let's hope to see a fix soon.

Let's hope to see a fix soon. Nah, I doubt these two are the same. This is an assertion failing, and the assertion itself is blatantly incorrect. This is so trivial that I'm not to bother to create a separate bug for this. Will have a patch up shortly.

Here's the patch. It's untrue that DecodePool::RequestDecode is only called from the main thread, so we shouldn't assert that. DecodeJob::Run can also call it. Furthermore, I don't see any reason to think that it's unsafe as long as we hold the decoding mutex (which we do, and we assert so).

Nothing's ever easy. This turned out to be more complex than it appeared. I'll create a new bug for this.

I'll fix this in bug 857367.

I believe that most recent star doesn't include the patch from bug 857367. Hopefully once things settle down a little we can confirm that this is now fixed. (Since it happened on Aurora we might want to consider uplifting bug 857367...)
