I was trying to change a JPEG image's orientation but the "Save" option does not seem to be working. The thumbnail that appears on gwenview looks as if the file has correctly been modified and going to the next picture in the folder and coming back to the "supposedly" modified JPEG shows the picture as if changes have been saved, but when opening the file in a new gwenview instance and/or another applications the image is shown unmodified.

This isn't happening with other image formats (GIFs, PNGs, etc.) or when doing "Save as".

I have run gwenview from the console and here is the relevant output:
