I can also reproduce this crash every time on Kubuntu 11.04. Detect and
recognize work as it should but Recognize faces immediately craches digikam
after pressing the ok button without even showing a progress bar for the
recognition to start.

New crash information added by DrKonqi

digikam (2.0.0-beta6) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:
I was using face detection. I chose Recognize faces in the Scanning faces
-window and digiKam crashed immediately after pressing Scan. Detect and
recognize faces  is not affected, it works as it should. Also, adding names
(manually) to faces previously found on pictures is no problem.

digikam (2.0.0-beta6) on KDE Platform 4.6.3 (4.6.3) using Qt 4.7.2

I had already done a "detect and recognise faces" scan previously and tagged a
few faces. When I came back to "recognise faces" digikam crashed.

If it crash imediatly, can you identify the image relevant of this crash during
scan. Look debug message when you run digiKam from a console (enable digikam
debug space using kdebugdialog program)

I have tried as you suggested with debug from console, and the problem seems to
be in disk I/O read error from the database. That is strange since the disk is
ok on checks, but I will test again to move the database on a new disk, and I
will test with the fresh database.

following is the debug output:

make a backup of digiKam4.db file, remove it, and restart digiKam. Look if
problem still there.

I just tried to remove digikam4.db and restarted Digikam. Had Digikam rescan
and remake a new digikam4.db. Also made a new face detection scan. After that
when trying to use the face recognition feature Digikam crashes again as
before.

I started digikam from command line and get this output from start to crash:

$ digikam

Btw, I always get the warning "(digikam:2702): GStreamer-CRITICAL **:
gst_debug_add_log_function: assertion `func != NULL' failed" when I start
digikam from command line and it in it self doesn't make anything crash so I
guess what's after that might be part of the crash.

digiKam do not use GStreamer stuff. KDELibs Phonon component can use it to
display video files preview in digiKam.

Perphaps your phonon/GStreamer install/config is broken ?

The GStreamer backend for Phonon works but gives that warning. Also do
the same if i start i.e Amarok from command line but Amarok works just
fine. Just to make sure I changed Phonon backend to VLC and digikam
still crashes like this but without the GStreamer warning:

$ digikam

still in use, all queries will cease to work.

FYI, I also tried to compile against opencv 2.1 instead of opencv 2.2 but it
didn't matter. Crashes the same way with either opencv 2.1 or 2.2. Had just to
try it...

did you disabled libdc1394 support in opencv ? There is just a flag to turn off
