Description Nico Kruber 2015-11-04 23:20:40 UTC 
Application: digikam (4.14.0)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-29-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

I updated file time stamps (last modified) and in turn, the thumbnail generator was working in the background (or maybe still from the import of >2000 images). During this background task, I tried to rename files to a common scheme when digikam crashed.

FYI: I'm using a MySQL database.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

crash not reproducible here.

The backtrace indicate a problem in KDE KIO component with Qt  core API. It sound like a binary compatibility problem with your system installation.

In other words : check your system.

Comment 3 Nico Kruber 2015-11-10 23:53:14 UTC 
Honestly, I'd suspect a race condition somewhere depending on the number of threads accessing the file/memory. I have no idea what I should check in my system - SSE2 should be available on a Core i5-3570K if you suspected that.

PS: sorry for the duplicate, I thought if it were, DrKonqi would identify it by the stacktrace...
Comment 4 caulier.gilles 2016-12-24 16:59:46 UTC 
digKam KIO slaves have been removed since 5.0.0 and replaced by a
multi-threaded interface.
