--- Comment #5 from Lorenzo Ferrillo lorenzofer@live.it --- EDIT:
"Also, but I need to test more, it seems to happen only if I have a non loadable plugin installed. (As for example Construction set specific plugins or plugins that miss a runtime component)"
And it block when its encountered (the unloadable plugin).
