Yeap, we do not need to load all the plugins to generate the list
every time an app starts.

Agree.

I do not think the first item here (when any Qt application starts) 
is needed if the second item is required rather than optional: AFAIK
gtk does not have this mechanism.

OK, I do admit that if we introduce the first item, some hassels may
be avoided. However, do we have to check the validation of the list
everytime an app starts?
