#2 Segfault

[Chedich]

You get a segfault when you try to add a image to the
list when you haven't loaded any image. This could
easily be fixed by checking if you have any image
loaded before you try to add it to the list.

Other misc. stuff to think about:
*Apply is spelled apply and not aply ;-)
*You shouldn't show the "add to list" and "export list"
buttons if the list feature haven't been added yet.

Otherwise just keep up the good work.
