gwenview intermittently saves image rotation changes

I use of gwenview to import .jpg images from camera, including creation of folder in my ~/Documents to contain the images. After import, I use gwenview to view images. When I rotate an image, and then try to save it, gwenview says that access is denied: this is new behavior, within the last few updates, as I have never seen this error before.

I look at the Permissions to the images' folder in Dolphin. I see Owner & Group "Can View & Modify Content" and Others "Can View Content". I change permissions for Others to "Can View & Modify Content", check the box "Apply changes to all subfolders and their contents", and click "OK". I verify at the command line that permissions are set to -rw-rw-rw- for all images.

I close and reopen gwenview to these same images. Now when I try to rotate and save, I do not receive an 'access' error message, but ONLY SOME of the images are saved. If I close and reopen gwenview, I can (usually) reliably save the first image I rotate, but then it may likely fail on the next altered images. Rotated images revert to their original positions. It does not matter if I rotate the images in full view or thumbnail view.

I know it's difficult to troubleshoot intermittent problems. I've tried to find a pattern in what is saved and what is not saved, but the only detail I can provide is that closing and reopening gwenview allows me to (most of the time) save the first image I rotate.

I frequently use gwenview and this is a new issue (within the last few months of updates). I found a similar bug from 2013: https://bugs.launchpad.net/ubuntu/+source/gwenview/+bug/1113410
