Comment 19 for bug 2013543

We've debugged a different issue which might eventually be the very same root cause - at least superficially it looks similar/related.
But OTOH we do not have enough evidence yet to mark bug 2004551 a real duplicate of this yet.

@Nick once you have a test build or something in proposed with this fix would you give us a ping to retest in regard to bug 2004551 as well please?
