Easy fix. The Qt4 GUI doesn't check if(g_EmulatorRunning) before calling the 
changeWindow() - the toggle fullscreen function. 

Changing void MainWindow::fullScreenToggle()
to this:
{
    if(core::g_EmulatorRunning)
        core::changeWindow();
}

will solve it. However, putting the check in the core as opposed to leaving it 
up 
to Gtk and Qt4 GUI is a better long-term fix.

New GUI API should prevent function from being called unless rom is running, 
closing issue.
