It crash in Qt4 without any particular reason :

I suspect a broken GDB backtrace which do not reflect the real problem.

Please run digiKam under a console through GDB, as it explained here :

https://www.digikam.org/contrib

...and take a new crash trace to see if it reproducible.

Gilles Caulier
Comment 2 caulier.gilles 2015-08-08 07:10:09 UTC 
I forget to said that the current trace do not reflect any face recognition dysfunction...
Comment 3 caulier.gilles 2015-08-13 08:01:51 UTC 
digiKam 4.12.0 is out.

https://www.digikam.org/node/741

Problem still reproducible ?

Gilles Caulier
Comment 4 Jeff Robinson 2015-08-13 16:43:17 UTC 
I cannot seem to reproduce the error.  Facial recognition/detection will still sometimes crash/close Digikam but does not generate an error message.  When I try to do the same from the command-line I only receive a message indicating that Dr. Konqi cannot be started.
Comment 5 caulier.gilles 2015-08-14 08:41:14 UTC 
run digiKam under GDB from a console to have a full trace of the dysfunction, as explained here :

https://www.digikam.org/node/741

You must also install digiKam debug package before.

Comment 6 caulier.gilles 2015-08-17 11:27:19 UTC

Comment 8 caulier.gilles 2015-08-19 04:43:41 UTC 
It's clear. It crash in Exiv2 when XMP metadata are parsed from image.

Please report this problem to Exiv2 bugzilla, including this last GDB backtrace.

http://dev.exiv2.org/projects/exiv2/issues

Also i suspect that you use Exiv2 0.24. Try to use Exiv2 0.25 instead (this require to recompile libkexiv2 with digiKam)

Gilles Caulier
Comment 9 caulier.gilles 2019-12-23 09:24:43 UTC 
Problem is fixed with new 7.0.0-beta1 through this long story from this bug

https://bugs.kde.org/show_bug.cgi?id=399923

You can test digiKam 7.0.0-beta1 with bundle available here:

https://download.kde.org/unstable/digikam/

Don't hesitate to give us a fresh feedback about his entry.

Thanks in advance
