Qt Version: 4.8.6
Operating System: Linux 3.14.8-200.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed: Working in Hugin creating a panoramic, and converting JPGs to PNGs in the background from a seperate script calling mogrify.  It was converting files in the digikam album directory.

The crash can be reproduced sometimes.

-- Backtrace:
Application: digiKam (digikam), signal: Bus error
