I also have not observed this on recent builds. As the original requestor, i
think this can be resolved. Unless others can still reproduce.

I experienced it in git master actually... but I can't reproduce at the moment.

I appear to get this problem too. It been in existence for a long time.
If you try to delete a second time it complains that the file isn't there but
then the thumbnail disappears.
Even worse though, when deleting photos that are apparently still there,
digikam then deletes a DIFFERENT (real) file and its impossible to restore it.

Not for me. I still experience the described behaviour.

I use digikam5.0.0-beta6

Steps to reproduce:
1)Create a new folder and add some images.
2)Go to the thumbnail view.
3) Move an image to trash.

Actual results
The image is removed from file system and the thumbnail doesn't exist anymore
in digiKam.

Expected results
Same as actual results.

When you said that the thumbnail do not exists, you want mean in thumbnail DB ?

It's true for all DB type ?

I'm surprised because a garbage collector to clean up DB entries about non
valid items have never been implemented, as i know...

Perhaps with an item removed from DK interface it will work, but what about to
remove file form hard drive by another application while DK session is down.
I'm sure that nothing is removed from the DB. But this case is fully relevan of
a future garbage collector tool for DB maintenance (i think another bugzilla
entry exist about this topic).

(In reply to caulier.gilles from comment #23)

I understand you now. I think I misinterpreted the issue faced by the user. I
just checked if thumbnail is removed the DK interface. The file still exists in
my Image table.

I apologize for the mistake.

Using 7fb769c27cf48408cf45cad65ba4330940663c05

I imported over 100 photos. Back in the main digiKam window, once importing
finished, I went to the new album, clicked on the last thumb, jumped 50 photos
back using the "left arrow" key, then I held shift and clicked on the first
photo in the album, to select the first >50, then I shift+deleted them. The
confirmation popped up, I agreed, and digiKam deleted the photos... only the
thumbnails have not disappeared.

Clicking F5 reloaded the album and then the deleted photos disappeared.

SO it's just a refresh problem. Right ?

Can you run digiKam from a console and post here the trace of operations when
you try again a similar deletion of files ?

Yes, looks like just a refresh problem.

I tried to reproduce the problem from a console now by just copying an existing
album under a new name, starting digiKam and deleting photos from the new
album, but the thumbs were correctly removed from digiKam, so I couldn't
reproduce. I will run it from a console the next time I import and delete and
report back to you.

Thumbnails remain after file deletion in version 5.0.0.0.Beta5 on Fedora Linux
24:
Version     : 5.0.0
Release     : 0.10.beta5.fc24

For example, I have 127 images in a directory. Thumbnails of all original
photos appear. After I process each image, I save a new version, e.g.,
pix-01.jpg saved as pix-01_v1.jpg. Later I remove the original photos, select
pix-01.jpg and move it to Trash.

The original file is moved to Trash, but the thumbnail remains in Album view.
When I try to delete the file a second time, an error message appears:

  File pix-01.jpg does not exist

When I try View -> Refresh, placeholder images (a bare tree at sunset?) appear
for thumbnails. Thumbnails and associated metadata seem to remain in any case.

Also, additional directories appear within my current directory in the Album
menu (left sidebar). They show different numbers of images. Now the left
sidebar shows four subdirectories ("albums") in the album I'm using, but
actually there are none.

The bug and another one (missing sidebar menu icons) appeared after I upgraded
Fedora 23 to 24 and then digiKam from version 4.x to 5.0.0.Beta5).

Swati,

For this file, outside the fact that a DB garbage collector need to be write to
clean up the database (there is one other bug entry about this topic), it must
miss a call to a sql query somewhere in thumbnails database interface when file
is removed from the collection.
