Description Andi Clemens 2010-02-21 09:07:21 UTC

Application: digikam (1.2.0)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I do simple things, at the moment I only crop images for a screenshot database at work. On every second crop & save (CTRL+X, simple crop) digiKam IE crashes. This is NOT true for showFoto, so it must be digikam related.

The crash can be reproduced some of the time.

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

Comment 3 caulier.gilles 2017-08-08 11:02:41 UTC

Since digiKam 5.0.0, KDirWatch was been replaced by QFileSytemWatcher. It will not reproducible.
