Did you marked some left file/folder for deletion? Do you have preview (View->Show Preview) active? If yes, can you try to sync with the preview disabled?
Created attachment 131062 [details] Screenshot
In French, from the menu toolbar, it should be "Vue" (fourth one) and "Afficher les aperçus"; try to sync with the checkbox unchecked.
Yes I checked this checkbox ... It was ans is still unchecked ! En Français pour être clair : L'option "afficher les apperçus" n'est pas active . Je cherche encore du coté du montage de la partition de destination en "luks" I'm still checking around the luks's partition mount of target partition. Maybe my problems are there.
The luks destination works better now and krusader also work better. I will come back if nessessary Excuses for the noise
New information was added with comment 4; changing status. The backtrace seems to indicate there is a problem in KrPreviewJob, possibly related to the timer events and/or nested event loop from the SynchronizeDialog.
*** Bug 424680 has been marked as a duplicate of this bug. ***
A possibly relevant merge request was started @ https://invent.kde.org/utilities/krusader/-/merge_requests/33
Status modified, Excuses for the noise. My last check of this problem goes off after I resolved a lucks problem (the destination was mounted on). Otherwise, I will come back here
Git commit 138e580a442aef8099c2c7c1b12bab709927c446 by Davide Gianforte, on behalf of Davide Gianforte. Committed on 23/03/2021 at 06:19. Pushed by gengisdave into branch 'master'. Remove a fileitem from the PreviewJob when it disappears When a file is updating (e.g. downloading, slow write, ...), Krusader crashes if the KIO::PreviewJob ends after the view is updated (no item to update).
