Summary: digiKam dies after tagging multiple files
Product: [Applications] digikam Reporter: Kristofer Rickheden Gustavsson <hackan301>
Component: Database-SqliteAssignee: Digikam Developers <digikam-bugs-null>
Status: RESOLVED FIXED    
Severity: crash CC: caulier.gilles
Priority: NOR Keywords: drkonqi
Version: 4.7.0   
Target Milestone: ---   
Platform: Ubuntu   
OS: Linux   
Latest Commit: Version Fixed In: 7.1.0

Description Kristofer Rickheden Gustavsson 2015-09-27 13:33:56 UTC 
Application: digikam (4.7.0)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.0-28-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Whenever I select a bunch of photos and apply a tag to them (let's say I wanna tag them with the tag sunny beach) Digikam tags the files, then a second later after tagging is complete digikam dies. When I open Digikam again all files are tagged, but any program settings I have made during the last session are gone.

The crash can be reproduced every time.

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