            Bug ID: 302437
          Severity: crash
           Version: 2.5.0
          Priority: NOR
          Assignee: digikam-devel at kde.org
           Summary: Crash when re-searching for faces
    Classification: Unclassified
                OS: Linux
          Reporter: axel.krebs at t-online.de
          Hardware: Compiled Sources
            Status: UNCONFIRMED
         Component: general
           Product: digikam

Application: digikam (2.5.0)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

When searching for faces, digikam crashes. 
In my collection, many faces are contained already. For some new pics, I
attributed names of faces, manually _before_ scanning for new ones.  

Can there be a conflict between _automatically_ detected faces and _manually_
detected faces when using the _same_ names??

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
