Description S. Burmeister 2011-07-15 01:02:44 UTC
Application: digikam (2.0.0)
KDE Platform Version: 4.6.95 (4.7 RC2) "release 1"
Qt Version: 4.7.3
Operating System: Linux 2.6.37.6-0.5-default i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
- What I was doing when the application crashed: While digikam was scanning for faces I already confirmed faces in the "unknown"-tag folder, i.e. clicked on the "ok" button which appears when one hovers the picture. While I was doing so digikam suddenly crashed.

I just updated to git some minutes ago.

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

Marcel, 

I think to have already seen this trace in another report, in the same condition. Right ?

digikam (2.1.0) on KDE Platform 4.6.5 (4.6.5) using Qt 4.7.3

- What I was doing when the application crashed:

I just selected one "unrecognized face", entered a name, and click on the button to validate the selection.
It happened several times, not necessarily when I validate a name : also when I click on the red cross ("this image is not a face")

Comment 6 Frederic Grelot 2011-08-27 17:06:26 UTC
Well, it seems that it happens every time I use "enter" to validate my choice.
Digikam does not crash if I click on the "validate tag" button.
Actually, I also saw that when I want to tag the photos, only half of those I selected get tagged : in this case, when I launch digikam after the crash, this is also true (half of my selected photos are tagged)

Comment 9 Marcel Wiesweg 2011-09-06 17:37:02 UTC
Anyone here who can reliably reproduce this bug (mark something as a new face, tag, crash), is following current git and ready to apply some patches to collect debug info?
Comment 10 Kristian Karl 2011-09-07 07:47:52 UTC
(In reply to comment #9)
Yes, I can.
I have a repro that always provokes a crash.
1) After scanning of faces,
2) I select the "unknown"-tag folder,
3) I apply a filter (using tags) to narrow down the scope of faces,
4) Select a face and choose a people tag,
5) Select some more faces,
6) Then I click on the "ok" button which appears when one hovers over the picture
7) crash occurs 

If this is good enough, I'm more than willing to pull from current (which branch?) git and ready to apply some patches and to collect debug info.

digikam (2.1.0) on KDE Platform 4.6.5 (4.6.5) using Qt 4.7.3

- What I was doing when the application crashed:

I was selecting the entire amount of RAW images in the Faces tab that the facial recognition had detected and was attempting to remove the tag from them when digikam crashed. I have been able to re-produce the issue.

I am curious if this has something to do with the other bug I have submitted https://bugs.kde.org/show_bug.cgi?id=279977 becuase I did notice a pattern that even though digikam crashed when selecting 100% of the 112 images when I re-started the application there were only 56 tags. So it seemed parallel to the other issue I had opened when selecting a range of images and only having half of them get untagged and then extraneous other images getting untagged as well.

digikam (2.2.0) on KDE Platform 4.6.5 (4.6.5) using Qt 4.7.3

- What I was doing when the application crashed:

I was browsing one's person recognized faces, but several of them (6 in a row) were wrong : I selected those, clicked on the red cross (this is not a face). Digikam crashed immediately.

Note : There were 6 pictures that I wanted to untag. when I did it the first time, digikam crashed but the first 3 were actually removed as I can tell after restarting digikam. When I wanted to untag those 3, digikam crashed again (but it actually untagged 2 out of 3). The last time, I untagged the 6'th image indivually, and digikam didn't crash.

Digikam is from recent GIT (fetched yesterday, appears as 2.2.0 in the about box)

You are sure to have included the two commits? The line numbers in the backtrace suggest you did not.
Comment 17 Kristian Karl 2011-09-11 19:16:38 UTC
Hi,

No more creash with latest.

I cloned latest fram master [1856bafe3262bc3594e16f2be65ed9d7eea09305], and built it using "cmake -DCMAKE_BUILD_TYPE=debugfull -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` .. "

I then tried my repro that alwayes rendered a crash before, but no crash. That's cool :-)
