Texture loading randomly crashes

Calling QTextureImage::setSource crashes randomly. First there is warning 

[Qt3DRender::GLTexture] No QTextureImageData generated from functor yet, texture will be invalid for this frame

Then the application crashes. Attached should be modified basicshapes-cpp example to demonstrate the issue. Repeatedly fastly click the check box to change the texture for the ball and quite soon you'll get the crash.
