Like a module has already been unloaded, and that code is being called. I just upgraded my -CURRENT amd64 machine, and I can't reproduce there either. But I did find something that may help. Extract Firefox, then edit embedding/base/nsEmbedAPI.cpp, and uncomment line 56. Rebuild Firefox, and see if this helps. We may need to add that for < -CURRENT.
