Application: digikam (4.12.0)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-36-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
When i'm adding some new metadata-information to my pictures digikam is doing well until short before finishing. The metadata is updated and fine when reopening digikam.

Maybe the problem is, that the collection is stored on an external drive??

The crash can be reproduced every time.

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