OK, then this patch use a straight QApplication. QLApplication is used only for Mac as far as I see. And use qApp only.

Does not help:

Are we really explicitly calling exit()?

Yes in lyx_gui.C:

void exit()
{
        delete lyxsocket;
        delete lyxserver;
        lyxserver = 0;

        // we cannot call qApp->exit(0) - that could return us
        // into a static dialog return in the lyx code (for example,
        // load autosave file QMessageBox. We have to just get the hell
        // out.

        ::exit(0);
}
