Comment 7 for bug 69878

to reproduce the fullscreen problem is very easy.

To lauch a video and apply the fullscreen mode, in this moment the E17 crash and propose a message box error :

you've too choice :

_ recover (F2)
_ exit (I don't remenber the exact touch)

if you press F2 the application is debugg and continu with the fullscreen (on my computer the sound don't apply here).
