Bug 227253

Summary: Instability after heavy image transfer/editing
Product: [Applications] digikam Reporter: Rudolf Leitgeb <Rudolf.Leitgeb>
Component: Albums-EngineAssignee: Digikam Developers <digikam-bugs-null>
Status: RESOLVED FIXED    
Severity: crash CC: andresbajotierra, caulier.gilles
Priority: NOR    
Version: unspecified   
Target Milestone: ---   
Platform: Unlisted Binaries   
OS: Linux   
Latest Commit: Version Fixed In: 5.7.0

Description Rudolf Leitgeb 2010-02-16 20:23:44 UTC
Application that crashed: digikam
Version of the application: 1.0.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-server x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I had multiple crashes today which all happened roughly the same way: heavy transfer of files (image download) or heavy editing in showfoto (many very large images in a row, crash usually during save or switch to next image). Unfortunately I can not provide you with a reliable method for recreating this behavior.

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