IMO g++ thinks that "Nepomuk::Resource res(KUrl(uri));" is a declaration of 
"res" as a function variable of type "Nepomuk::Resource(KUrl(uri))".

Again IMO, "Nepomuk::Resource res((KUrl(uri)));" should do what you want.

That's why programming language designers will always insist that undecidable 
grammar is bad.
