If I start a random slideshow in a directory with tousands of jpg images named 000001.jpg - 056545.jpg, by opening one of these pictures from krusader for example, and then start a slideshow, the first image is one I have opened, but then it shows the images in random order. But if i start a random slideshow again starting from any picture, after the first image it start to show me the images in exactly same order like it was showed in first slideshow. 
Here is an example to be more clear:
first slideshow:
opened 033565.jpg, slideshow: 033565.jpg, 005453.jpg, 042334.jpg, 023154.jpg,...
gwenview closed,
second slideshow:
opened 046456.jpg, slideshow: 046456.jpg, 005453.jpg, 042334.jpg, 023154.jpg,...

It looks that it occures mainly when a large number of pictures is used.
