[digikam] [Bug 346097] New: when tagging a face it hangs or will no longer load pictures from thumbnail

            Bug ID: 346097
           Summary: when tagging a face it hangs or will no longer load
                    pictures from thumbnail
           Product: digikam
           Version: unspecified
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Face Management
          Assignee: [hidden email]
          Reporter: [hidden email]

When I tag a face, one of the following happens:
- Digikam hangs. The trace shows memory exhaustion
- Digikam seems to run normally, but when I click on any other thumbnail, it
will no longer show the enlarged picture (with message displayed in a small
box: 'failed to load image').

I am now running V4.9, but the issue existed also in the previous versions
(V4.8 and V4.5). My platform is Windows7, 64 bits

Reproducible: Always

Steps to Reproduce:
1. start Digikam
2. my photos are organised in directories per date
3. select a date (Album) and pick a thumbnail without face tag
4. on the picture, do the tagging, add name

Actual Results:  
hang or 'failed to load', as stated above
Sometimes the tag has been applied correctly (to be seen after restarting
Digikam), sometimes the tag shows up (as shown under the thumbnail and in the
tag list on the right of the screen) but the box around the face (that is the
position of the face) has been lost

Expected Results:  
no hang, tag stored correctly

Hi, could I suggest to put this workaround (renaming the recognition.db file)
in the release notes? That would have avoided this duplicate bug: I checked the
release notes and the fixed bugs list and I noticed the face recognition bug
was marked as closed. But I did not go through the whole bug to find the
workaround at the end.
The renaming worked just fine.

I see this bug as well. First, I observed it in Digikam 4.7.0 (as shipped with
ubuntu 15.04). Then, I realized that this bug in marked as fixed in 4.9.0
(https://bugs.kde.org/show_bug.cgi?id=338176).

After installing Digikam 4.11.0 on KDE Development Platform 4.14.6 I still
observe this bug. I add this comment here and not in 338176 because I don't do
face recognition, I simply assign a name to an already existing tag (as
described by  Derk Korevaar above).

I think this bug is not resolved yet.

System:

- Ubuntu 15.04, 64bit
- KDE Devel. Platform 4.14.6
- Digikam 4.11.0
- Pictures in Digikam: ~ 40k
- # of face tags: a couple of 1000
