Comment 1 for bug 252096

I think the error here is that we initialise the preferences dialog outside
the function that calls the preferences dialog. This means that once you
have killed it the object doesn't exist anymore - so object.show makes no
sense.

I will take a look at it later and see if there is something that can be
done.
