Looks like we are not doing a deferred release of the wrapped native because GetRuntime() is NULL. Weird.
Boy would it be handy if we could record & replay this ...

bent, we should probably take a look at this. This is becoming ridiculously frequent.
Second most common failure on mozilla-central for the week, but who's counting?
Ugh, who broke the world while I was looking elsewhere?!
This seems bad.

Why block on this? It seems a narrow problem in indexdb. We should try to fix, but I don't see us holding a release over it.
Bah, wrong tab :-/

Somehow XPCWrappedNative::GetRuntime() is returning null.

Or mDoingFinalization is prematurely false, as I pointed out on IRC.

/be
bent pointed out a suspicious range, and this particular push looks like it could cause this (maybe, just guessing for now).

Apparently that's not it (or not all of it) - I pushed a backout of that to try in http://tbpl.mozilla.org/?tree=MozillaTry&rev=cbff81817339 and still hit this on 2 of 4 runs, pretty much the normal incidence.
Thanks a lot for investigating Phil.

This crash has apparently starting happening more frequently after http://hg.mozilla.org/mozilla-central/rev/52ffeed74f96, for reasons unknown.  That patch might have made plugin tests run faster and changed timing, but I can't even wildly guess beyond that.

The new crashes look identical to the old ones, so I don't know what to do other than supplicate Ben/Andreas for some attention on the existing bug.  I don't think it's good policy to back out unrelated patches for changing timing and tickling existing bugs more often.

Maybe this bug is easier to repro now after 52ffeed74f96?  Ben/Andreas, maybe one of you guys could check out a 10.5 slave and investigate?

How do you know it's null?  We know that it's failing to enter:
