Application: digikam (3.5.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic i686
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
After running face detection and recognition, did quite a bit of work verifying, correcting, and rejecting face suggestions.  Then ran face recognition without detection.  The progress bar advanced to 22% within five minutes' time.  Three hours later, progress was still at 22%.  I canceled the recognition process and, immediately after canceling, exited digiKam by pressing the window decoration in top right ('x' button).  Crash.

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