Description S. Burmeister 2010-10-28 18:09:59 UTC
Application: digikam (2.0.0-GSoC2010 (rev.: 1188100))
KDE Platform Version: 4.5.2 (KDE 4.5.2) "release 10"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.5-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Digikam had found some faces and I entered a tag for the name of a person. That name stays in the linedit where "Who is this?" was before, so I continued to hover pictures with that person on it and clicked the "ok button" for those pictures that showed that person and the reject button for those pictures that did not show any face. After some dozen images digikam just crashed.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault

Comment 1 caulier.gilles 2010-10-28 18:24:49 UTC
Crash appear in libface/libkface.

Which svn revision you use with these libraries ?

Code is not yet stabilized here. It's important to know this information.

Gilles Caulier
Comment 2 S. Burmeister 2010-10-28 18:28:59 UTC
libkface is Rev: 1190651
libface Rev: 260
Comment 3 Marcel Wiesweg 2010-10-28 18:35:09 UTC
When I wrote the mail "ready for testing" it was stable, really. ;-)

In the meantime, Alex has rewritten the recognition part, which did not work at all before. And it's crashing, obviously.
Comment 4 caulier.gilles 2010-11-24 09:13:21 UTC
digiKam 1.6.0 is out:

http://www.digikam.org/drupal/node/550

Please update and check if this entry still valid.

Thanks in advance

Comment 5 Marcel Wiesweg 2011-01-18 15:07:10 UTC
Sven, same here: Still applicable?
Comment 6 caulier.gilles 2011-06-16 16:36:18 UTC
*** Bug 275827 has been marked as a duplicate of this bug. ***
Comment 7 Gareth 2011-06-16 17:03:09 UTC
My bug, I was able to reproduce 4-5 times (and each time the backtrace/bug reporter marked this as the probable match). 
I then moved ~/.kde/share/apps/libkface/database/libface-config.xml, and was unable to reproduce the bug from that point. File was 0 size
Comment 8 Marcel Wiesweg 2011-06-19 16:33:11 UTC
Git commit ec062a1c349b3ed0d8d308925dbe257960a8bdb6 by Marcel Wiesweg.
Committed on 19/06/2011 at 15:41.
Pushed by mwiesweg into branch 'master'.

Main part of recognition is currently disabled for stable release, also disable
updating part which obviously crashes as well sometimes.

Comment 9 caulier.gilles 2011-07-02 10:02:01 UTC
digiKam 2.0.0 RC is out. Please check if crash is reproducible with this version.

Thanks in advance

Comment 10 Marcel Wiesweg 2011-09-25 13:34:40 UTC
Eigenfaces recognition is disabled due to major issues. Hoping for Amey's HMM code.
Comment 11 caulier.gilles 2017-12-16 11:10:26 UTC
This crash is not reproducible use current 5.8.0 pre-release bundle available
here :

https://files.kde.org/digikam/

I close this file now. Re-open it if necessary.
