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: digikam-devel at kde.org
Reporter: derkkorevaar at online.nl
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
