When downloading images one can tell digikam how to format the filename, i.e. suffix and prefix and adding a number starting at x.

If one downloads pictures into a folder and they get all the same filename, except for the appended number, and then wants to add more images to that folder in a second download from the camera, digikam/KDE tells the user that file xyz_1.jpg already exists, showing both images in the "do you want to overwrite" dialogue. If one uses the "suggest new name" button in the file-dialogue xyz_11.jpg is suggested, that file does also already exist so xyz_111.jpg is suggested.

If one clicks on "rename" the same dialogue pops-up again, this time only showing one image but still telling the user that the file xyz_1.jpg already exists.

So it seems that the file is not renamed and there are some issues with appending a number and the file-dialogue.
