            Bug ID: 347628
           Summary: Can't remove "legend" field when updating metadata
           Product: digikam
           Version: 4.5.0
          Platform: Mageia RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Metadata
          Assignee: digikam-devel at kde.org
          Reporter: npomarede at corp.free.fr

When using my Samsung NX camera, all photos get tagged with the exif tag 
Image Description               : SAMSUNG CSC
(as reported by exiftool)

When such images are added into digikam, digikam will automatically copy this
"image description" tag into its database and this can be seen in the right of
the screen when clicking on "legends / tags" ("légendes/étiquettes" in french).
Then in the "description" tab we see 2 boxes:
 - title
 - legend
In "legend", the "SAMSUNG CSC" text is visible.

Now, I want to remove this info, because it has no value to me and I'd rather
have this field empty (plus it's displayed under each photo thumbnail, which is
not useful).

Unfortunattely, I can't find how to remove this information for all the photos
in this album.
I tried this :
 - exit digikam
 - use exiftool to remove this "image description" field on all images
 - restart digikam
-> "SAMSUNG CSC" is still displayed in the legend window

I tried with one of the image the menu "Image / Read metadata again from the
image", as I thought it would update this info ; no luck, it's still there.

Note that if I use "Image / Metadata / modify metadata", I can see that in the
exif tab the "description" and "legend" field are empty, so my images were
correctly updated by exiftool.

So, I thought I would remove all photos and import them again. I clicked on the
album, chose delete from disk. All the files were gone.

Then I exited digikam, copied my album directory (with all "image description"
tags removed) into digikam's photo dir, started digikam. It correctly detected
the album, imported it, but then the "legend " tag was still there :( It seems
it was not deleted from digikam database, although I deleted all the photos ?

Is this a wanted behaviour or is this a bug ? How can I force digikam to forget
about those "SAMSUNG CSC" legend text that don't exist anymore in any file of
my album ?

Thanks
