Description Randall Rude 2024-03-11 17:09:38 UTC

STEPS TO REPRODUCE
1. Load the demo database.
2. Click Events, then click fun.
3. Select both images and open the annotation dialog with CTRL-2.
4. Unselect the "fun" event and click Done.
5. Now delete one or more images to trigger the segfault (eg. click Home, People, and select and delete an image).

OBSERVED RESULT
KPhotoAlbum segfaults.

EXPECTED RESULT
KPhotoAlbum shouldn't segfault.

ADDITIONAL INFORMATION
AnnotationDialog::Dialog::slotDiscardFiles() is calling AnnotationDialog::ImagePreviewWidget::reconfigure() even though the annotation dialog is closed.  AnnotationDialog::Dialog() is not clearing m_origList when it is accepted.

This was a nasty one ;-) Please check if this fixes it, and re-open if not!

Wow, that was fast.  And it seems to be fixed.  Good work!
