Description Steven Aiello 2006-05-12 01:30:50 UTC

Version:           0.8.2-beta1+svn534957 (using KDE KDE 3.5.2)
Installed from:    Gentoo Packages
Compiler:          gcc version 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8) 
OS:                Linux

Whenever digikam encounters a jpeg image it crashes. I have tried multiple jpegs from my Canon EOS Rebel XT, and all make digikam crash. I removed all images from my digikam album, and then copied the jpeg image that I use for my desktop background, and it too causes digikam to crash. I removed all images from my digikam album and copied a png image, no crash, saw a nice thumbnail in digikam.

I have tested the following versions of digikam:
0.7.4 - works, no crash.
0.8.1 - crash.
0.8.2-beta1+svn534957 - crash.

digikam -v produces:
Qt: 3.3.4
KDE: 3.5.2
digiKam: 0.8.2-beta1+svn534957

I belive this bug is found only on the Gentoo GNU/Linux distribution. I did see others with this/simular issue (http://forums.gentoo.org/viewtopic-p-3309378.html#3309378).

Per Gilles request I performed a gdb backtrace:

Comment 1 caulier.gilles 2006-07-03 12:37:33 UTC

digiKam crash out of scanlib during images scanning. It's impossible. I suspect that something is broken during linking or something like that. 

Can you recompile digiKam using --enable-debug=full and without any optimizations.

Re-install and re-start digiKam inside gdb and look if it crash again.

Comment 3 caulier.gilles 2006-07-20 07:45:22 UTC

ralph, 

Steven talking about the scan image process at digiKam startup, not the scanner kipi plugin. Please report you problem in a new B.K.O file into kipi-plugins area...

Gilles Caulier

Comment 4 caulier.gilles 2006-12-12 09:24:04 UTC

Steven, 
 
This crash still reproductible using digiKam/DigikamImagePlugins 0.9.0-RC2 and Exiv2 0.12 ? 
 
Thanks in advance for your feedback. 
 
Gilles Caulier

Comment 5 caulier.gilles 2007-04-20 14:37:07 UTC

Steven,

What's news about this crash. It still reproductible using digiKam 0.9.1 ?

Gilles Caulier

Comment 6 Jan Schenk 2007-04-20 17:03:48 UTC

Gilles,
I had the exact problem as Steven described it, and it seems solved with 0.9.1!
Thanks alot,
