There is 2 crash handler in this report. I cannot figure which one is the right one. Sound like it's a problem to save a JPG image on disk.

Please run digiKam on a console trough GDB to get a better backtrace, as explained here :

With next 5.1.0 release, a lots of investigations have be done around OpenCV face module integration with digiKam Face Engine.
See bug #365202 history for details.
I close this file now. Don't hesistate to re-open if necessary.
