            Bug ID: 300407
          Severity: major
           Version: 2.5.0
          Priority: NOR
          Assignee: digikam-devel at kde.org
           Summary: Tags not written to files properly, old tags left over
    Classification: Unclassified
                OS: Linux
          Reporter: bugs at seeitmyway.org
          Hardware: Gentoo Packages
            Status: UNCONFIRMED
         Component: Tags
           Product: digikam

Since I started using digiKam a few years ago my tagging habits changed and I
wanted to clean the tags up and make them consistent, so I rearranged them into
neat hierarchies and delete the old tags.
I also wanted to recreate digikam.db, to start afresh, but I wanted to keep the
db just in case, so I did a Settings > Database Migration. The old db was about
50MB, the migrated one was 21MB. It cleaned some stuff out, good, that was the
point.

Now I closed digiKam, deleted digikam.db (the old one, the new one was kept in
backup elsewhere) and restarted digiKam. After scanning my photos, I noticed
that the old tags were back.
I selected all the photos in each collection (I have 3 collections), in the
Captions/Tags tab I selected Information > Template > my new template, and
clicked on More > Write metadata to each file.
This took a good hour or two.
I did not enable "write metadata to raw files" so I presume digiKam wrote
metadata to all files except my PEFs, whose metadata it stored in the
digikam.db file.

Now I closed digiKam, deleted digikam.db, and restarted it. It should only show
the new tags since it would read them from the non-raws, and the raw files
should have no tags since the db was deleted. Well that's not entirely the
case.

I see the new tags, but I also see the old ones. In fact every first photo in
every album has the old tags and the new tags. Every other photo has just the
new ones.
e.g.:
/media/photos/2012-05-01/001.jpg will have both old and new tags
/media/photos/2012-05-01/002.jpg - 100.jpg will have just the new tags.

I can't use the photos until the old tags are removed, e.g. my old template
with my old defunct email address, therefore this is a major bug.
