           Summary: Tags not deleted from XMP, using Tag-Side-View on the
                    left
           Product: digikam
           Version: 2.3.0
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Tags
        AssignedTo: digikam-devel at kde.org
        ReportedBy: px79 at crazymonkeys.de


Version:           2.3.0 (using KDE 4.7.3) 
OS:                Linux

Using the tag-view on the left side of the screen does not remove the tag from
the xmp container in the file.


Reproducible: Always

Steps to Reproduce:
1. Assign three tags to a picture: A, B and C
2. open the tag view on the left screen side
3. select tag "B"
   -> you can see your picture in the middle part of the screen
4. rightclick tag "B" on the left side, select "Delete Tag" and confirm
deletion
   -> the tag in the left view disappears
5. select tag "A" in the left view to see the picture again
6. select the picture in the middle view
7. have a look at "Metadata -> XMP" on the right side:
   you can see "digiKam schema -> Tags List -> A, B, C"   (Tag not deleted from
XMP-Data)
8. now choose: "Image -> Reread metadata from image"
   -> tag "B" appears in the tag-view on the left side again

Actual Results:  
After step 4. the tag "B" is still present in the XMP part of the JPEG. Also
confirmed with a hex editor.

Expected Results:  
After step 4. the tag should have been removed from the XMP container.

I use "Metadata Writing Mode: Write to image only".

The tags seem to be removed from sqldb, since digikam does not show them
anywhere in it's GUI. But I have not looked at the database.

Tags are also _not_ removed from XMP-data in the file, if you reorganise your
tags via drag'n'drop in the tag-view on the left side.

This bug seems to reside in digikam since 1.1.0. With this version I did some
reorganisation as mentioned above and created some "ghost-tags" in June 2011.

Using the "Caption/Tags" view on right-side to remove tags, works fine.
