Sentry Crash Report:

Description Martin Johnson 2011-11-20 20:14:05 UTC 
Application: digikam (2.2.0)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
Im using Digikam in swedish, so I don't know the english labels. Sorry.
I have made a search for faces in my photocollction and get a lot of faces with tag "personer" -> "okända" ("unknown"?). When I select a bunch of faces, from five to fifteen, using + in upper left corner of picture or selecting by CTRL-left click i often get a crash like this.
Sometimes, I can select faces and type in a nametag, or selecting an existing nametag and get these faces to move from "okända" ("unknown"?).

The crash can be reproduced some of the time.

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

Comment 1 vato 2011-11-29 03:55:07 UTC 
Application: digikam (2.2.0)
KDE Platform Version: 4.7.3 (4.7.3) "release 10"
Operating System: Linux 3.1.0-1.2-desktop i686
Distribution: "openSUSE 12.1 (x86_64)"

I can confirm that it happens to me as well whenever I select more than one image under People/Unknown with <ctrl>+left click. Sometimes it is possible to select more than two images but quite often selecting the second image crashes digikam.
Comment 2 caulier.gilles 2011-11-29 12:09:05 UTC 
And it still reproducible with 2.3.0 release ?

Comment 3 vato 2011-11-29 19:24:27 UTC 
Sorry for the delay. I had to compile 2.3.0 myself (the openSUSE package does not work).

The above mentioned behavior is still reproducible on 2.3.0.
Comment 4 Prasad Murthy 2011-12-10 10:47:30 UTC 
It also happens in version 2.3.0. I am using kubuntu 11.10 and ppa:philip5/extra

phoenix-firebird: the essential part of the backtrace is missing, please see here on how to get a better backtrace: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
Comment 6 caulier.gilles 2011-12-14 13:40:30 UTC 
Martin,

Can you reproduce the crash using digiKam 2.4 ?

Gilles Caulier
Comment 7 vato 2011-12-15 00:04:53 UTC 
I don't know about 2.4, but the crash still happens under 2.4.1
Comment 8 Prasad Murthy 2011-12-17 09:49:29 UTC 
Check comment 28 on this bug report https://bugs.kde.org/show_bug.cgi?id=262596
Comment 9 caulier.gilles 2011-12-17 10:05:48 UTC 
Phoenix: crash in 262596 is not the same than here ...

Comment 10 Prasad Murthy 2011-12-18 06:52:30 UTC 
I checked the above stated problem by martin with digikam version 2.4.1 and it didn't crash ,i guess martin might have run the face recognition process in the background while he was selecting the photos and the background process crashed. It would be helpful if martin could provide some info.
Comment 11 vato 2012-03-29 04:02:46 UTC 
Since version 2.5.0 (KDE 4.8.1), Digikam is not crashing anymore when selecting several images under People/Unknown.
