http://hg.mozilla.org/mozilla-central/annotate/3285e030d9c0/ipc/glue/InputStreamUtils.cpp#l51 MOZ_CRASH("Input stream is not serializable!"); Called on a DOM blob GetInternalStream: http://hg.mozilla.org/mozilla-central/annotate/3285e030d9c0/dom/ipc/ContentChild.cpp#l948 This sounds familiar, but I don't remember whether it was subsequently fixed. bent do you remember, or know who should take this?

Oh, maybe bug 902271?

Seems likely. Josh, are you going to try this again? Or do we need to find another owner?

Yeah, I'll start looking at this again this week.
