Looks like mTransation was null: http://hg.mozilla.org/mozilla-central/annotate/5d654a428c97/netwerk/protocol/http/nsHttpConnection.cpp#l1136

I don't see any reason CloseTransaction() couldn't get called from OnInputStreamReady (perhaps with EOF or just framing complete) and then again from OnOutputstreamReady as a forced detach on shutdown (as seen in the stack) before things were fully torn down.. just checking mTransaction for null appears sufficient to fix it.
