It crash in Face Detection process.

Which configuration did you use ? libkface version ? Maintenance tool settings ?

It miss line #0 to #5...

Please install all debug packages : digikam, libkface, libkexiv2, opencv and Exiv2. Re run digikam from a console into GDB as explained here :

https://www.digikam.org/contrib

... and try to reproduce the crash. The trace to report will be printed in the console...

Comment 3 Jose Gómez 2015-07-25 09:49:39 UTC 
On the configuration, I set it to detect all faces, and as far as I remember I used an accuracy setting of 100 (not 80% sure, as I did another run at 100% which did not detect any face in thousands of images).

My libkface3 version is 4:14.12.3-ubuntu1.

I just installed the libkexiv2-dbg package (I already had symbols installed for digikam, and there are no symbols available in my distribution for libkface3).

Will try to reproduce the issue via gdb, as suggested. But it will take time, as each run takes many hours.
Comment 4 Jose Gómez 2015-07-26 13:21:12 UTC 
Created attachment 93746 [details]
Backtrace after the crash

As requested, I've installed all the -dbg packages available, reproduced the issue from within gdb and posted the backtrace. I hope it is useful. Let me know if I can do anything else to help debug the crash, which seems to happen every time I run the full maintenance.
Comment 5 caulier.gilles 2015-07-26 13:50:34 UTC 
It crash in Exiv2 shared lib, especially in TIFFLoader, not in libkface.

It's a duplicate of bug #350423. Read well instructions that i give in this bug.
