It happens if you select a folder with many subfolders and files in it. The editor parses through all of them and that can sometimes.. take a while.
When I'm trying to open my pictures folder in the import editor I have the same.. it needs about 10 seconds to get all the images checked.
What you can try is to change the name of the directory it's currently pointing to. When you open the editor again, it usually switches back to a default folder. After that you can change the name back.
