I have been using DigiKam for more than 10 years. Since around the end of 2017 / beginning of 2018, I began to notice corrupted photos in my album.

I've added 53 photos to my album yesterday. All the photos were absolutely normal. Then I've added a tag to these photos.
After checking, I found that 8 photos were corrupted.

openSUSE VERSION = 42.1
DigiKam 5.5.5.0

The tag is written in Cyrillic.
