Jerry,
Thanks for your answer.
I'm sorry I haven't been very lucid in my questions.
I don't have ant problem with the helper applications for any 
extensions. My problem is that:
1. I cannot change the default helper as it always uses Virus Scanner as 
it's default application which of course is ridiculous on a Linux system 
(but I have clamav installed as I'm paranoid).
2. It doesn't come - as does nautilus - with a list of other helper 
applications but shows my home directory.
I think both actions are not what is expected and moreover in nautilus 
it works correctly.
Greetings,
Joep
