[Jaap]

https://bugs.kde.org/show_bug.cgi?id=326742

            Bug ID: 326742
           Summary: Scanning for faces crashes
    Classification: Unclassified
           Product: digikam
           Version: 3.4.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: [hidden email]
          Reporter: [hidden email]

Application: digikam (3.4.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic i686
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I was tagging my photos for almost 2 hours. Durring a rescan with option "Skip
images already scanned" the application crashed. It looks like it's related to
the files which are handled. Maybe some unreadable or corrupt file?

- Custom settings of the application:
Using mysql database

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

--- Comment #4 from Gilles Caulier <[hidden email]> ---
With next digiKam 4.1.0, i fixed libkface to handle all C++ exception (and not
only OpenCV exception).

So, at least, digiKam must crash lesser now. If you want to review this entry
again, use current implementation from git/master, or wait next 4.1.0
release...

Thanks to update your feedback

Committed on 18/06/2014 at 14:22.
Pushed by cgilles into branch 'master'.

Libkface now depand of last stable OpenCV library version 2.4.9
This prevent internal crash int Cv:Algorithm that we cannot handle in libkface
as exception.
Now, Face Recognition do not crash but still report Exception at training
operations, especially about wrong Cv:Matrix size :

digikam(8673)/digikam (core)
Digikam::DImg::load:"/mnt/data2/photos/GILLES/NEW/Adrien/2010-04-13/20100413_009.jpg"

It still a problem somwhere, but it's better than previous state.

With next digiKam 4.1.0, a lots of improvements/fixes have be done around face
management. Please give us a fresh feedback.

Note i recommend to delete face recognition database to prevent dysfunction due
to possible wrong data store in this container. Look where file is located in
my computer :
