Bug 273122

Summary: Digikam2-beta5 crashes while scanning faces
Product: [Applications] digikam Reporter: terri.bugs
Component: Faces-EngineAssignee: Digikam Developers <digikam-bugs-null>
Status: RESOLVED FIXED    
Severity: crash CC: caulier.gilles
Priority: NOR    
Version: 2.0.0   
Target Milestone: ---   
Platform: Ubuntu   
OS: Linux   
Latest Commit: Version Fixed In: 2.3.0
Sentry Crash Report:

Description terri.bugs 2011-05-12 14:12:02 UTC 
Application: digikam (2.0.0-beta5)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
digiKam was scanning faces from my collection (~5,000 items) and I was using Nautilus to rename some folders, which are also digiKam albums (some changes in foldernames did not appear correctly even after rescanning the collection). Just before the crash I added 5 folders (500 MB) to the collection via Nautilus Drag and Drop, which had worked without problems on previous occasions. This crash is similar to bug 266086 in the sense of what I had been doing since starting digiKam.

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

When I restarted digiKam after filing this bug, I got the first-time-user screen 'Welcome to digikam 2.0' asking where my collection is etc. However, after answering the questions digiKam seemed to find the old database and started using it.
Comment 2 Marcel Wiesweg 2011-05-13 22:48:02 UTC 
Ok, another unchecked Album pointer stored in ImageInfoJob.
Comment 3 Marcel Wiesweg 2011-05-21 14:52:39 UTC

Comment 4 caulier.gilles 2011-07-02 10:02:20 UTC 
digiKam 2.0.0 RC is out. Please check if crash is reproducible with this version.

Thanks in advance

Comment 5 caulier.gilles 2011-11-03 12:42:18 UTC 
digiKam 2.2.0 is out since few weeks. Crash still valid with this version ?

Gilles Caulier
Comment 6 terri.bugs 2011-11-05 20:28:54 UTC 
This hasn't happened with the 2.2.0 so far (haven't had that much time for testing), so this bug can be closed.
