Michael Krüger, thank you for your answer. I'm also using a self-compiled version of Qt free version (not the commercial one) and I've just enabled -qt-plugin-mysql and -opengl. I do this as an habit because I didn't find the latest version of Qt in the repositories of the former versions of Kubuntu. I don't know how it is now because I didn't even check (I'm using Kubuntu 9.04). But I will install the repository version of Qt to check if it solves the problem.
Matthias, I'll let you know when I'll have tried what Michael said. Thank you !
