Comment (by Oliver.Freyd@…):

 I had the exact same problem, playback would crash immediately
 if OpenGL or VAAPI profile was set, only Normal would work.
 Only after finding that "Qt" main mode instead of "Auto"
 was incompatible with "OpenGL" playback mode I could fix the problem.

 Why not disable the selection of these playback modes, or give a hint
 that you need "Auto" main mode in order to use OpenGL or VAAPI playback?!

 Would be more user-friendly...
