I briefly looked into this yesterday. I saw that we fell into this: http://hg.mozilla.org/mozilla-central/index.cgi/annotate/tip/dom/src/base/nsDOMClassInfo.cpp#l5084 if statement, bailing out of nsDOMConstructorSH::PostCreate. I haven't been able to reproduce the assertion since then, so I'm not exactly sure what's triggering the if statement and I forgot, at the time, to look at the JS call stack.
