Comment 1 caulier.gilles 2013-02-06 15:49:53 UTC 
It crash in-deep in libpng/libc when thumbnail are created.

Please try with a more recent version as last 2.9.0

Comment 2 caulier.gilles 2015-06-30 08:05:18 UTC 
New digiKam 4.11.0 is available :

https://www.digikam.org/node/740

Can you reproduce the problem with this release ?
Comment 3 Heinrich Seebauer 2015-07-04 19:11:49 UTC 
Downloaded 4.11 as requested and tried to compile it on a separate VM - BTW not exactly a simple task.
After several hours I got it up & running - it showed up as Version 4.6.0.
On my (physical) PC version 4.6.0 had been installed already from the suse repos.
Can someone please explain this annoying difference? Is 4.11 == 4.6? Or does it simply show the wrong version number?

On 4.6.0 the bug does not show up.
Comment 4 caulier.gilles 2015-07-04 22:11:56 UTC 
digiKam 4.11.0 versus 4.6.0 = around 300 bug fixes
