Summary: Performing multiple scans and recognises causes crash
Product: [Applications] digikam Reporter: Gareth <gareth.glaccum>
Component: Faces-RecognitionAssignee: Digikam Developers <digikam-bugs-null>
Status: RESOLVED FIXED    
Severity: crash CC: caulier.gilles

Version: 2.0.0   
Target Milestone: ---   
Platform: Fedora RPMs

Sentry Crash Report:

Description Gareth 2011-06-14 16:10:12 UTC 
Application: digikam (2.0.0-beta6)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.35.4-28.fc14.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
This is reported as a possible duplicate, because the initial scan was working fine.

1) Perform scan of albums (CR2 raws) (>1000)
2) Start initial tagging of around 25 images
3) Then click the scan option, and choose recognise faces.
4) Digikam immediately crashes.

What I think may be different to the other bugs, is that the scanner option was available to me to choose, even whilst another scan was going on. This may or may not be a fair bug, if two scans cannot be performed at the same time, then the scan option should not be selectable

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