In general nautilus isn't threadsafe. However, you're of course free to
do whatever you want in a thread, as long as you only interact with
nautilus on the main thread (i.e. via idles). 

I don't know how the python threading affects this though. You'd have to
talk to the nautilus-python people about that.
