[vlc-devel] [PATCH 3/3] qt: fix setScreen might crash on wayland when entering fullscreen

>From the ISO C++:

The zero-initialization [...]. Constant initialization [...], Otherwise such a 
variable is initialized the first time control passes through its declaration; 
such a variable is considered initialized upon the completion of its 
initialization. If the initialization exits by throwing an exception, the 
initialization is not complete, so it will be tried again the next time 
control enters the declaration.  [... concurent / recursive init ....]

Both functions are called from the UI thread, so QGuiApplication::platformName 
has been set before and concurent initialisation could not happen.

But I don't mind storing it in the class if you prefers.
