-- Information about the crash:
I applied some tags to an image and selected the next one in the album. I was asked if I want digiKam to save the changes I made. I checked the box to never ask this again and clicked "save". Afterwards, digikam crashed.

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