Hello again. My apologies that it took me this long to answer but I was busy throughout the last week and to my personal embarrassment I forgot about this bug report.
Anyway, I did have a special german character in the absolute path ("ü", full path: "/home/username/Downloads/Kubuntu/PGP Schlüssel") and removing it also stopped the crashing. I tried to reproduce the bug with software-properties-gtk but it can handle the special character without any noticeable problems. I found another possible bug in software-properties-kde while testing it: When I remove a PGP key, it says that there has been an error while removing the key but the key is removed anyway. As with the other bug, software-properties-gtk doesn't seem to suffer from this bug.
