Segmentation violation with video reader

When I run the following video reader code;

% Read one frame at a time.
for k = 1 : handles.xyloObj.NumberOfFrames
  set(handles.text8,'Visible','on');
  handles.mov(k).cdata = read(handles.xyloObj, k);
end

MATLAB crashes and gives the following error message :
