The UI freezes ("Preparing image - please wait") if I try to open a
document with the "Unpaper images" option enabled.

Hi,

I have just fixed this. It seems that Unpaper was forked but Fedora (which I am using) is still using the original one, that's why I had version 0.X and you have a version > 1.

I installed the fork and the problem is that it no longer supports having the same output image name as the input's.

I have filed an issue about this in Unpaper's GitHub:
