Bug ID: 419079
Summary: Star rating on TIFF images destroys the image
Product: digikam
Version: 7.0.0
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: critical
Priority: NOR
Component: Plugin-FilesIO-TIFF

destroyed TIFF images (within .zip file)
SUMMARY
star rating on TIFF images randomly destroys the images.
I did the star rating to aprox >200 images. After this 8 images were destroyed
- they are almost black with some stripes.
I tried the same on .jpg images but it seems to me that this is specific to
TIFF format.
STEPS TO REPRODUCE
1. have a view on many images (TIFF format) (e.g in preview).
2. do star rating on many images - do it fast so that processing is queued
3. wait until all ratings are processed
4. update the view (F5) this will reload thumbnails and shows the destroyed
images - if there are any.
It seems to me that there is a problem with multithreading?
I have attached one destroyed image (zipped)
OBSERVED RESULT
several images are destroyed --> image can be loaded but is almost black
EXPECTED RESULT
images should remain unchanged - except the star rating
