I read the stack trace as the thread has received the shutdown signature, then it starts to create a memory report which requires to start a new thread, and it's blocked by https://hg.mozilla.org/mozilla-central/annotate/d4e11195e39888686d843a146a893eb0ebf38224/xpcom/threads/nsThread.cpp#l676

So I guess this could be a potential deadlock issue?
